gmain: do not wakeup the wakeup registration

Browse Source 
Do not wakeup immediately for our own context wakeup poll registration.

g_main_context_add_poll_unlocked() will call g_wakeup_signal() to wake
up the loop waiting in poll(). Doing so during context creation will
create an extra wakeup for the first poll().

Skip the wakeup call if it is the wake_up_rec registration. No other
sources/caller should ever reach that condition.
