init: don't spew warning about late g_thread_init()s if GLib >= 2.23.2
init: don't spew warning about late g_thread_init()s if GLib >= 2.23.2

Late g_thread_init() is fine with newer GLib versions and done automatically
from g_type_init() there, so don't warn if the application hasn't called
g_thread_init() yet when gst_init() is called with new GLib versions.

Fixes #608398.
