filemerge: move removal of `.orig` extension on temp file close to context

The place where the `.orig` extension is removed in `_maketempfiles()`
doesn't make it clear that it's the backup path, which is why we have
a comment in the code explaining it. Let's instead move it out of the
function and close to where we get it from `backup.path()`, so that
becomes clear.
