typing: adjust `mercurial.util.iterlines()` to accept any `Iterable`

In a local pytype run on the extensions, this fixes:

    File "/mnt/c/Users/Matt/hg/hgext/phabricator.py", line 788, in maketext:
        Function mercurial.util.iterlines was called with the wrong arguments [wrong-arg-types]
             Expected: (iterator: Iterator[bytes])
      Actually passed: (iterator: list)
      Attributes of protocol Iterator[bytes] are not implemented on list: __next__
