As the comment needed explanation, that it's about temporary build
files, this should do better.
Thanks again to @lethalman for pointing that out.

If no config.nix.storeDir has been set, don't fall back to "/nix/store"
but use builtins.storeDir instead so we always should end up with the
correct store path no matter whether config.nix.storeDir has been set.

After patching up the shared libraries in c420de6 to use absolute paths,
there are still some libraries left which do not get an absolute paths
assigned.
Those libraries are the ones which have an absolute path outside of the
Nix store, so we assume that they're build products of the current build
and make them absolute by prepending "$out/lib" or "$lib/lib" (depending
on whether it's a multiple output derivation or not) to its basename.
So for my test case, the resulting library paths now look like this:
/nix/store/...-libblockdev-1.3/lib/libblockdev.so.0
/nix/store/...-glibc-2.21/lib/libm.so.6
/nix/store/...-dmraid-1.0.0.rc16/lib/libdmraid.so.1.0.0.rc16
/nix/store/...-libblockdev-1.3/lib/libbd_utils.so.0
Which is perfectly fine and everything gets resolved correctly after
importing the library using GI.
However, I didn't test it against other libraries and programs, so this
still needs testing, especially for Darwin.

The gi-r-scanner is generating a list of shared libraries that are
referenced in the shared-library attribute of the <namespace/> element
of the GIR file. However, this attribute only contains the names of the
libraries and not the full store paths, like for example while preparing
to package libblockdev, the following items were included in the
shared-library attribute:
/nix/store/...-libblockdev-1.3/lib/libblockdev.so.0
libm.so.6
libdmraid.so.1.0.0.rc16
libbd_utils.so.0
Unfortunately, loading such a library without setting LD_LIBRARY_PATH is
going to fail finding libm.so.6 and libdmraid.so.1.0.0.rc16.
Now the first attempt at solving this was to put absolute paths of all
the libraries referenced in the shared-library attribute, but this also
led up to including paths of build-time shared objects into that
attribute:
/nix/store/...-libblockdev-1.3/lib/libblockdev.so.0
/nix/store/...-glibc-2.21/lib/libm.so.6
/nix/store/...-dmraid-1.0.0.rc16/lib/libdmraid.so.1.0.0.rc16
/tmp/nix-build-libblockdev-1.3.drv-0/.../utils/.libs/libbd_utils.so.0
This of course is not what we want, so the final solution is to only
use the absolute path whenever it is a Nix path and leave the library
name as-is if the path doesn't reside within the store, like this:
/nix/store/...-libblockdev-1.3/lib/libblockdev.so.0
/nix/store/...-glibc-2.21/lib/libm.so.6
/nix/store/...-dmraid-1.0.0.rc16/lib/libdmraid.so.1.0.0.rc16
libbd_utils.so.0
The downside of this approach is that if not even the output path of the
library is in LD_LIBRARY_PATH, even loading of libbd_utils.so.0 could
fail, so we need to patch the loader as well.
