libpayload: Increase accuracy of timeout period for media init.
When bringing up media, we claim to wait for up to 30 seconds for a
device to respond to our TEST_UNIT_READY command. Actually, we can wait
far longer because we do not take into account execution delay.
To improve timeout accuracy, make use of gettimeofday(), which calculates
time based upon a CPU counter. This improves the user experience
slightly when certain non-working USB devices are used.
BUG=chrome-os-partner:22345
TEST=Manual on Peppy w/ FCR-HS3 SD card reader. Verify that command
timeout occurs in ~30 seconds, rather than ~10,000 seconds.
