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:

"""Tool read primitive events from a pipe to produce a catapult trace. Usage: Terminal 1: $ catapipe.py /tmp/mypipe /tmp/trace.json Terminal 2: $ HGCATAPULTSERVERPIPE=/tmp/mypipe hg root <ctrl-c catapipe.py in Terminal 1> $ catapult/tracing/bin/trace2html /tmp/trace.json # produce /tmp/trace.html <open trace.html in your browser of choice; the WASD keys are very useful> (catapult is located at https://github.com/catapult-project/catapult) For now the event stream supports START $SESSIONID ... and END $SESSIONID ... events. Everything after the SESSIONID (which must not contain spaces) is used as a label for the event. Events are timestamped as of when they arrive in this process and are then used to produce catapult traces that can be loaded in Chrome's about:tracing utility. It's important that the event stream *into* this process stay simple, because we have to emit it from the shell scripts produced by run-tests.py. Typically you'll want to place the path to the named pipe in the HGCATAPULTSERVERPIPE environment variable, which both run-tests and hg understand. To trace *only* run-tests, use HGTESTCATAPULTSERVERPIPE instead.
