pfctl -s all should not print operating system fingerprints

Hello tech@,

'pfctl -s all' shows also all OS fingerprints loaded
to kernel, while it should report only the number of
fingerprints. This is a regression in 7.9 I've accidentally
introduced.

the issue has been noticed and reported by David Adams on bugs [1].

The same diff I've posted to bugs@ few weeks ago is found further
below.

OK to commit?

thanks and
regards
sashan
