net-firewall/fwknop: Drop python2-only module, cleanup .a

The fko python module is python2-only. Most(?) uses of fwknop do not
need the optional python module at all. Removed it and if that causes
problems, will deal with it.

Also added a USE=static-libs flag, and clean up .a if it is not set.

+fwknopd supports several backends: firewalld, iptables, ipfw, pf, ipf.
+You can set the desired backend via FIREWALL_EXE option in fwknopd.conf
