Fix wrong formating to "Vote Delay Minutes" when delay above 60s

Unless I'm being silly, shouldn't the % just be / here?

We still want it to wrap around 60 as that's our current unit of time. FormatTime is likely the most correct fix here.

FormatTime is not appropriate and a time stamp must be used

Some solutions:

1. limit sm_vote_delay to 3600 seconds to cover the only corner case
2. or move function int FormatTimeDuration(char[] buffer, int maxlen, int time) from nextmap.sp to another place (maybe in timers.inc as stock) and use FormatTimeDuration to format the delay on basevotes.sp and funvotes.sp

Ok corrected as your suggest
