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:

This extension is useful for testing Mercurial behavior when various network events occur. Various config options in the [badserver] section influence behavior: closebeforeaccept If true, close() the server socket when a new connection arrives before accept() is called. The server will then exit. closeafteraccept If true, the server will close() the client socket immediately after accept(). closeafterrecvbytes If defined, close the client socket after receiving this many bytes. closeaftersendbytes If defined, close the client socket after sending this many bytes.
