[gobject-introspection] Add uid_t, gid_t, dev_t to integral type conversions

[Johan Dahlin <johan src gnome org>]

commit 26ac70c37e4ea2f7e1caf8cebed3577695ce20e3
Author: Colin Walters <walters verbum org>

    Add uid_t, gid_t, dev_t to integral type conversions
    
    Continuing where we were going with pid_t, define a few more POSIX
    types by converting them to their fundamental integers.  See
    commentary in patch for more explanation on rationale.
