WARNING: func_lookup_file is not something tied to a module. Rather, it
sits on a level below the module layer.

Witness: func_lookup_file is also used by the --copy-file option, and the
handling of --copy-file ignores modules.

I would put the implementation of func_lookup_file into a class
GNULibFileSystem, whose semantics I have described in
http://lists.gnu.org/archive/html/gnulib-tool-py/2012-06/msg00005

GNULibModuleSystem can inherit from this class, or GNULibModule can contain
a reference to a GNULibModuleSystem.
