Henrich Hartzer 87bf0aaba8 Remove COMPAT_FREEBSD4/5/6/7/9 from MINIMAL and FIRECRACKER kernel configurations
FIRECRACKER is not a legacy config, so remove the really old FreeBSD
versions from it. MINIMAL has a similar history, and limited target
audience which has little to no overlap with really old binaries. Either
of these is really easy to get additional binary compat with the include
directive, so balance things better. Leave GENERIC alone.

# MINIMAL -- Mostly Minimal kernel configuration file for FreeBSD/amd64
#
# Many definitions of minimal are possible. The one this file follows is
# GENERIC, minus all functionality that can be replaced by loading kernel
# modules.
#
# Exceptions:
# o (non-loaded) random is included due to uncertainty...
# o Many networking things are included
#
# For now, please run changes to these list past imp@freebsd.org
#
# For more information on this file, please read the config(5) manual page,
# and/or the handbook section on Kernel Configuration Files:
#
# https://docs.freebsd.org/en/books/handbook/kernelconfig/#kernelconfig-config
#
# The handbook is also available locally in /usr/share/doc/handbook
# if you've installed the doc distribution, otherwise always see the
# FreeBSD World Wide Web server (https://www.FreeBSD.org/) for the
# latest information.
#
# An exhaustive list of options and more detailed explanations of the
# device lines is also present in the ../../conf/NOTES and NOTES files.
# If you are in doubt as to the purpose or necessity of a line, check first
# in NOTES.
