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.
