p7519: allow running without watchman prereq
p7519 measures the performance of the fsmonitor code. To do this, it uses the installed copy of Watchman. If Watchman isn't installed, a noop integration script is installed in its place. When in the latter mode, it is expected that the script should not write a "last update token": in fact, it doesn't write anything at all since the script is blank. Commit 33226af42b (t/perf/fsmonitor: improve error message if typoing hook name, 2020-10-26) made sure that running 'git update-index --fsmonitor' did not write anything to stderr, but this is not the case when using the empty Watchman script, since Git will complain that: $ which watchman watchman not found $ cat .git/hooks/fsmonitor-empty $ git -c core.fsmonitor=.git/hooks/fsmonitor-empty update-index --fsmonitor warning: Empty last update token. Prior to 33226af42b, the output wasn't checked at all, which allowed this noop mode to work. But, 33226af42b breaks p7519 when running it without a 'watchman(1)' on your system. Handle this by only checking that the stderr is empty only when running with a real watchman executable. Otherwise, assert that the error message is the expected one when running in the noop mode.
