libobs: Fix module search to ignore . and ..

When globbing for modules, the intent was to ignore the . and ..
directories that might also be included in the glob search.  It was
mistakenly doing a string compare on the 'path' variable which contains
the full path, rather than the 'file' variable which just contains the
found file itself, so the string compare always failed.
