mp_common: improve OSD/status time formatting 

Allow negative times. Timestamps can be negative, and we actually
display negative time for other reasons too, such as when waiting for
the old audio to drain with gapless audio.)

Avoid overflows with relatively large time values. (We still don't
handle values too large for int64_t.)
