Make build-many-glibcs.py flush stdout before execv.
When build-many-glibcs.py re-execs itself with execv, any buffered
output on stdout may be lost (in particular, messages intended to go
to a bot's log about the re-exec taking place).  This patch makes it
flush stdout before execv, similar to the flush before running a
subprocess from the bot that is done to ensure output appears in the
right order.

	* scripts/build-many-glibcs.py (Context.exec_self): Flush stdout
	before calling execv.
