[dockers] Rename 'docker-snmp-sv2' to 'docker-snmp' (#4699)

The `-sv2` suffix was used to differentiate SNMP Dockers when we transitioned from "SONiCv1" to "SONiCv2", about four years ago. The old Docker materials were removed long ago; there is no need to keep this suffix. Removing it aligns the name with all the other Dockers.

Also edit Monit configuration to detect proper snmp-subagent command line in Buster, and make snmpd command line matching more robust.
