Move our fnmatch/glob implementation into gl/lib

The gl subdirectory contains our local versions of gnulib module
implementations, so move fnmatch* and glob* from lib to gl/lib.

* gl/modules/make-glob: Add a proper Files: section.
* lib/.gitignore: Delete unnecessary ignore file: lib is empty.
* .gitignore: Add lib/ as an ignored directory.
