monitor: Use USR1 signal to dump debug data
Similar to what fan control is already doing, this commit adds a handler
for the USR1 signal to write debug data to /tmp/fan_monitor_dump.json.
The data being written is the same data saved in an event log - the
current sensor status plus any of the Logger class's logs.
Example output, which shows fan0 recovering from previous faults:

monitor: Capture 'in range' status in sensor FFDC
This field provides information if the current sensor tach reading is
considered healthy or not without having to manually do the math based
on the current input and target values that fan monitor does.
