Revert a 1-line change that I never intended to commit. However,
leave in place the PORTREVISION bump and the other change to the RC
script, which I did intend to commit, but in a separate revision,
with this change message:

devel/buildbot-worker rc script fails to start worker

Running "service buildbot-worker start" on FreeBSD 11.0-RELEASE fails with
the error "warn 'run_rc_command: cannot run -worker_program". The reason is
because name contains a hyphen. This causes the following line in rc.subr
to expand incorrectly:
command=${_override_command:-$command}

The solution is to change name to "buildbot_worker".
