tools/rv: Fix substring match when listing container monitors

Browse Source 
When listing monitors within a specific container (rv list <container>),
the tool incorrectly matched monitors if the requested container name
was only a prefix of the actual container (e.g., 'rv list sche' would
incorrectly list monitors from 'sched:').

Fix this by ensuring the container name is an exact match and is
immediately followed by the ':' separator.
