gobject: Cast various inverted bitfield constants to unsigned

Browse Source 
This fixes `-Wsign-conversion` warnings, though I’m not sure why the
compiler is emitting them. The signed/unsigned status of flag enum
members is not particularly well defined in the C standard (and even
less well understood by me), so just do what seems necessary to shut the
compiler up.

The benefits of enabling `-Wsign-conversion` across the codebase
hopefully outweighs this noise.
