[glib/wip/mutexes: 46/58] GSystemThread: port 'self' 'join' and 'create'

[Ryan Lortie <ryanl src gnome org>]

commit 03c371dbf3e4aab96a3618d4a77eabf3f9144783
Author: Ryan Lortie <desrt desrt ca>

    GSystemThread: port 'self' 'join' and 'create'
    
    Switch 'self' 'join' and 'create' from using the vtable to being called
    via normal g_system_thread_* internal API (implemented in each of
    gthread-{posix,win32}.c).
    
    Again, we can put NULL in the vtable since these were never used from
    gthread.h.
