fix pf.conf prototype

Cédric Berger-2
In rev 1.29 of /etc/pf.conf, "pass quick" has been replaced
by "set skip" for lo and $int_if.

I think that for lo, it makes a lot of sense to use set skip,
but for $int_if, it is a poor default choice, because it break
the subsequent ftp-proxy line:

#rdr pass on $int_if proto tcp to port ftp -> port 8021

if you uncomment the above line using /etc/pf.conf prototype, it
won't work and it's not obvious why. I therefore suggest
reverting part of the previous patch.
