Magit has seen plenty of development since version 0.7, but for some reason
there haven't been any new releases. This version bump updates the expression to
build a current version of Magit directly from the Git repository.
This change adds buildInputs 'autoconf' and 'automake'. These tools are required
only because we aren't building from a proper release tarball. Once version 0.8
comes out, these dependencies can be dropped again.
