[Kernel] [TOS 6.4.1] Seccomp is not enabled in the kernel

I am trying to make use of seccomp. And apparently you can install package from Reforis packages but it's not enabled in the kernel so we can't use it.

lxc-start debian 20230811182430.924 INFO seccomp - seccomp.c:use_seccomp:1174 - Seccomp is not enabled in the kernel

root@router:~# zcat /proc/config.gz | grep -i seccomp
CONFIG_HAVE_ARCH_SECCOMP=y
CONFIG_HAVE_ARCH_SECCOMP_FILTER=y
# CONFIG_SECCOMP is not set
root@router:~# uname -r
5.15.120

Please make a fix.
