verify-fingerprint: returns "found in known hosts" when host is a subset of a verified host

[Isha-Sharma]

Current behavior

If a host is a subset of a verified host, verify-fingerprint returns with "found in known hosts" and exits.

Example:
Verifying test.domain.com
known_hosts mytest.domain.com
Output "Key found in known_hosts."

Steps to reproduce

Verify fingerprint for test.domain.com when mytest.domain.com is in your known_hosts

Suggested Solutions

Use an exact match when filtering in known_hosts
