MT#61856 media_player: calculate cache times in us

The only caller of `media_player_get_cache_times()`
does comparisons based on microseconds, but the called
function to calculate `mtime` and `atime` does this in seconds.

Hence the result is used incorrectly, because it compares
that value against `rtpe_now - rtpe_config.db_expire_us`,
which is again in microseconds.
