kexec_load: classify into Security family with its sibling
kexec_load(2) and kexec_file_load are documented together on the same
man page and both load a new kernel for later execution by reboot(2).
kexec_file_load was already FamilySecurity, but kexec_load fell through
to FamilyMisc. Move kexec_load to FamilySecurity so the siblings share
a family. Kind classification was already correct: kexec_load takes raw
user pointers (KindNull, no fd/path) while kexec_file_load takes fds
(KindFd); the return value (long 0/-1, no byte count) stays UNCLASSIFIED.
Update docs/syscall-tracing-plan.md to match, regenerate artifacts, and
add lock-in tests for the family and UNCLASSIFIED return of both kexec
syscalls plus reboot.
