ecore: force pthread_join even when main loop isn't running.

ecore: force pthread_join even when main loop isn't running.

pthread_create can fail if to much pthread are pending. As pthread_join
is only called when the main loop can flush the async call list, there was
a possibility for edje_cc to run out of thread due to that. We know
force the flush of the async call list and so call pthread_join when
pthread_create fail.
