Support early exit from wait_until_keyword_succeeds in wait_state

Currently, wait_until_keyword_succeeds() doesn't provide a means for a
programmer to exit early for a special condition.

This commit contains a solution whereby a signal handler can be invoked
to set a global wait_early_exit_message to indicate to check_state and
wait_state that an early exit should be made and it should count as a
failure.
