MT#58511 monit: check for unix socket instead of TCP port

As of git rev 511e1f69cc91 in templates (see "MT#58452 monit: Use a Unix socket for the httpd control access"),
monit no longer listens on port 2812 but uses a Unix socket instead.

Fixes:

| not ok 848 - Port: tcp:2812: listening: doesn't match, expect: [true] found: [false]
