scmutil: rewrite docstring for filecache

The old docstring was incorrect in that it said that subsequent
calls perform a stat() and refresh the object if things change.
This is not how things work: __get__ populates obj.__dict__[self.sname]
with the result of the decorated function and returns this value
without validation on subsequent calls, if available.

The correct usage of this type is kinda wonky. It would probably
benefit from a refactor. But I don't have time to do that right
now. But we can change the docstring so others aren't entrapped by
its lies (like I was when using repofilecache in a Mozilla extension).
