[high fps] fix blinking in all games

[SuperSamus]

Fixes both interval and animation speed. (jak1 previously only had a fix for the former.)
This should close #3518, and one of the issues of #1499.

The solution is not the cleanest. The results are going to be wrong in case the FPS doesn't reach the maximum set.
A better solution would be to make random-time a float, so that it can be subtracted by time-adjust-ratio, but I don't know if changing a type for this purpose is allowed here. Tell me if I should do that instead.

Tested only on jak2.

Can one of the admins verify this patch?

Looks like your one failing check is just a newline/formatting issue.
