profiles: Gracefully deal with packages containing an etc/ symlink.
This fixes a bug whereby 'guix package -i gcc-toolchain' would fail in 'build-profile'. This is because in 'gcc-toolchain', etc/ is a symlink, and so the 'scandir' call in 'unsymlink' would return #f instead of returning a list. Reported by Andreas Enge <andreas.enge@inria.fr>. * guix/build/profiles.scm (ensure-writable-directory)[unsymlink]: Append "/" to TARGET before calling 'scandir'. * tests/profiles.scm ("etc/profile when etc/ is a symlink"): New test.
