pfctl: fix out-of-bounds access
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).
