pfctl: fix out-of-bounds accessHEADmain
If pfctl is called with "pfctl -a ''" we read outside of the anchoropt buffer. Check that the buffer is sufficiently long to avoid that. Maintain the existing (and desired, because it's used as such in /etc/periodic/security/520.pfdenied) behaviour of treating "-a ''" as a request for the root anchor (or no anchor specified).
