fastboot: Use clock_gettime(CLOCK_MONOTONIC) in now()
If the system time changes during the execution of fastboot we might
see some strange output such as:
Sending sparse 'super' 4/20 (254972 KB) OKAY [-516.263s]
Fix it by changing now() to use clock_gettime(CLOCK_MONOTONIC).
I confirmed that all callers of now() are using it for relative time
and not time since the epoch.
