pam.d: install hard link with same mode as target

Previously when using NO_ROOT we recorded a METALOG entry for the
pam.d/ftp hard link with a different file mode than the link target
pam.d/ftpd, which is not permitted.

This change is similar to 1dbb9994d4dd for .profile

Remove telnetd

The telnetd codebase is unmaintained and has a number of quality
issues. Telnet has been largely supplanted by ssh. If needed, a port is
available (net/freebsd-telnetd), but a more maintained implementation
should be prefered.

While the telnet client suffers from the same issues, it is deemed
to be of lower risk and is required to connect to legacy devices, so
it remains.
