gdb/fortran: Add test for module variables in 'info variables' output 

Recent work from Tom Tromey to better handle variables with associated
copy relocations has fixed a Fortran issue where module variables
wouldn't show up in the output of 'info variables'.

This commit adds a test for this functionality to ensure it doesn't
get broken in the future.

gdb/testsuite/ChangeLog:

	* gdb.fortran/module.exp: Extend with 'info variables' test.
