[FM] FM recording time will display incorrectly when recording time is beyond 60 minutes

Launch FM from Launcher and power up FM -> Select "Start
Recording" in options menu, check the Recording Timer Text
("00m00s" is OK) -> Wait for FM recording more than 60 minutes
(e.g. 61 minutes 20 seconds), click power key to unlock screen
and check the recording timer text in FM record, the recording
timer text will be "00m20s".

The fix is to follow SoundRecorder's way to show recording timer.
