sysutils/pftop: build against native libpfctl #182

So we have a "libpfctl" for abstraction but the base system
a particular "libpfctl" originates from does not provide the
libary so we need to jump through a couple of hoops to embed
the libary into the pftop build in order to retain compatibility
on stable/13?
