expo: Split bootflow_menu_run() into two pieces

Browse Source 
Split the starting piece of this function into bootflow_menu_start()
and the polling part into bootflow_menu_poll() so that it is possible
for the caller to be in control of the event loop.

Move the expo_destroy() call into the caller.
