Subject: [PATCH] girepository: Fix a memory leak of a mapped file

This was introduced by me in commit
1eec66c8989f418e5254808dc899ae540ba0e89d, as the ownership transfer
semantics of `gi_typelib_new_from_mapped_file()` were not blatant.

Signed-off-by: Philip Withnall <pwithnall@gnome.org>

Helps: #3237
