iotests/207: Filter host fingerprint 

Commit e3296cc796 made the ssh block
driver's error message for fingerprint mismatches more verbose, so it
now prints the actual host key fingerprint and the key type.

iotest 207 tests such errors, but was not amended to filter that
fingerprint (which is host-specific), so do it now.  Filter the key
type, too, because I guess this too can differ depending on the host
configuration.

Fixes: e3296cc796
       ("block: print the server key type and fingerprint on failure")
