typing: drop annotations on `mercurial/logcmdutil.walkopts` attributes

Pytype 2021-09-09 must have learned some things about `@attr`, because while
these were presumably required to help it before (c1d0f83d62c4::9a26fea2b518 and
c11099cc1de4::224c786f4fce), these instances now get flagged as an assignment
mismatch:
