p7519: improve check for prerequisite WATCHMAN
The return code of command -v with a non-existing command is 1 in bash and 127 in dash. Use that return code directly to allow the script to work with dash and without watchman (e.g. on Debian). While at it stop redirecting the output. stderr is redirected to /dev/null by test_lazy_prereq already, and stdout can actually be useful -- the path of the found watchman executable is sent there, but it's shown only if the script was run with --verbose.
