libpayload/libc/console: Flush input driver buffer on init

When console input driver registers itself, perform flush of input
buffer to avoid interpreting any stale key presses before libpayload
is run.

BUG=b:37273808
TEST=Verified that any key presses in serial console before payload is
up do not have any effect after the payload starts running.
