LibJS+LibUnicode: Handle flexible day periods on both sides of midnight

Commit ec7d535 only partially handled the case of flexible day periods
rolling over midnight, in that it only worked for hours after midnight.
For example, the en locale defines a day period range of [21:00, 06:00).
The previous method of adding 24 hours to the given hour would change
e.g. 23:00 to 47:00, which isn't valid.
