trimmer: use g_match_info_free instead of g_match_info_unref

The build fails with glib 2.22:

    trimmer.c: In function ‘compile_and_match’:
    trimmer.c:201:3: error: implicit declaration of function ‘g_match_info_unref’; did you mean ‘g_match_info_free’? [-Werror=implicit-function-declaration]
       g_match_info_unref(*match_info);
       ^~~~~~~~~~~~~~~~~~
       g_match_info_free

The g_match_info_unref function is only available from glib 2.30.  Use
g_match_info_free instead, which does the same for our use case.
