FortranCInterface: Fix misuse of IS_NEWER_THAN in timestamp check
When using a file system which only has second resolution timestamps,
there is a reasonably high likelihood of timestamps being the same.
The IS_NEWER_THAN test returns true when timestamps are the same,
so don't redo detection when they match exactly.
