glib-compile-schemas: Fix various memory leaks

Browse Source 
Spotted while running `make check` under Valgrind. While it’s not
necessary to fix memory leaks in glib-compile-schemas (since it’s a
utility which runs briefly then exits), fixing them makes more
legitimate leaks in the Valgrind output more obvious, and means we can
be sure there aren’t leaks in the underlying GLib/GIO code which
glib-compile-schemas is calling.
