unionrepo: fill in uncompressed length of revlog entry
It can be either -1 or a valid length, but shouldn't be None. IIUC, we can
simply trust the length retrieved from the revlog to be overlaid. I don't
bother thinking whether the compressed length can be copied as well. We'll
need to fix it later.
