kext: fast-track split-tunnel proxy packets on loopback

Browse Source 
Add PM_SPLIT_TUN_PORT (719) to fast_track_pm_packets so that redirected
packets arriving at the local split-tunnel proxy are permitted immediately
by the kext, matching the existing behaviour for the SPN port (717) and
the DNS port (53). This prevents internal proxy connections from being
reported to Portmaster and appearing in the connection monitor UI.

Also simplify fast_track_pm_packets by removing the redundant
match-on-direction branches, which were identical for Outbound and
Inbound.

Bump kext interface patch version to 2.1.1.0.
