Do not pollute top-level, but do provide allow the derivations to
be accessed for debugging and reuse if necessary.

As has been done in https://github.com/NixOS/nix/pull/4944
This introduces the boehmgc_nix and boehmgc_nixUnstable attributes
which are useful for external packages that link with Nix and its
boehmgc.

I've also updated the URL for the RISC-V patch in case the content of
the old URL will change (not sure if that's possible after a merge
request is merged but now that the patch is upstream it seems like a
good idea regardless; and the content has actually already changed so
the old hash wasn't correct anymore).
Note: This update likely causes some issues when running an application
that has a direct dependency on Mesa (e.g. Sway and XWayland) and was
compiled against a different Nixpkgs revision. See 7106fca0fe4 for more
details regarding that issue.
Note: The update to Mesa 21.0.2 was reverted (25ae1fd29f8) because it
caused major issues with Sway (segfault on startup [0]).
This is still the case and might affect all packages that directly
depend on "mesa" (for libgbm or libglapi) but it only causes issues when
the package depends on a "mesa" version that differs from "mesa.drivers"
used for "/run/opengl-driver/". I've noticed this while testing Mesa
updates with the NixOS option "hardware.opengl.package" (as usual)
instead of rebuilding my whole system (which would work). Unfortunately
this can/will likely also cause issues when mixing different channels,
using Flakes/Overlays, etc.
The cause of this should be similar to [1] ("mesa" updates now cause the
same issues that "glibc" updates already do, maybe triggered by certain
Mesa changes) and some additional discussions is in [2],[3].
Note: Don't backport this to NixOS 21.05, at least not without careful
consideration.
