selftest/firmware: Add selftest timeout in settings

Browse Source 
The firmware tests would always time out for me. Add a correct timeout,
including details on how the value was reached. Additionally allow the
test harness to skip comments in settings files and report how long a
given timeout was.

# The async firmware timeout is set to 1 second (but ends up being effectively
# 2 seconds). There are 3 test configs, each done with and without firmware
# present, each with 2 "nowait" functions tested 5 times. Expected time for a
# normal execution should be 2 * 3 * 2 * 2 * 5 = 120 seconds for those alone.
# Additionally, fw_fallback may take 5 seconds for internal timeouts in each
# of the 3 configs, so at least another 15 seconds are needed. Add another
# 10 seconds for each testing config: 120 + 15 + 30
