filemerge: remove `uselocalpath` argument from `_maketempfiles()`
The `localpath` argument is unused if `uselocalpath` is false, so we
can use `None` as a sentinel value for the variable instead and remove
extra `uselocalpath` argument. That's not much of a win, but it's a
small step towards further improvements.
