remove obsolete kernel debugging script
For quite some time kgdb has been internally handling FreeBSD kernel module state; add-on scripts and tools are not needed. asf(8) served a similar purpose to this script and was removed in r335222. PR: 229046 Reported by: jhb Sponsored by: The FreeBSD Foundation
