discovery: Recurse into directories pointed to by a symlink.
Reported by Christopher Baines <mail@cbaines.net>
and Alex Kost <alezost@gmail.com>
at <https://lists.gnu.org/archive/html/guix-devel/2017-06/msg00290.html>.
* guix/discovery.scm (scheme-files): When ENTRY is a symlink that
doesn't end in '.scm', call 'stat' and recurse if it points to a
directory.
* tests/discovery.scm ("scheme-modules recurses in symlinks to
directories"): New test.
