Hello build bot (Jenkins),

lib/hardwaremain: Call poll_futures

This CL makes the ramstage state machine poll the futures after each
callback and during stage transitions. This will keep the futures
progressing throughout the boot process. This is a no-op for platforms
that don't set FUTURES_EXECUTOR.

BUG=b:177909625
TEST=Boot guybrush and see payload read/decompress drop by 23 ms.
