Enable `CONFIG_SECURITY` support on `6.6.X-linuxkit`+

[PhilipSchmid]

Description

When trying to run eBPF-based security tools, like Tetragon (also see related Tetragon GH issue), on Docker Desktop-based KIND clusters, we're seeing issues like the following one, as the Docker Desktop (4.28.0 (139021), Server Version: 25.0.3) shipped Kernel 6.6.16-linuxkit doesn't have CONFIG_SECURITY=y set at kernel compilation time:

... aborting could not load BPF programs: failed prog /var/lib/tetragon/bpf_execve_bprm_commit_creds.o kern_version 394768 loadInstance: attaching 'tg_kp_bprm_committing_creds' failed: creating perf_kprobe PMU (arch-specific fallback for \"security_bprm_committing_creds\"): token __arm64_security_bprm_committing_creds: not found: no such file or directory

It's not set on the Docker Desktop included VM:

$ docker run -it --rm --privileged --pid=host ubuntu nsenter -t 1 -m -u -n -i sh -c 'cat /proc/config.gz | gunzip | grep CONFIG_SECURITY'
CONFIG_SECURITY_DMESG_RESTRICT=y
# CONFIG_SECURITY is not set
CONFIG_SECURITYFS=y

However, on the upstream linuxkit/linuxkit project it's already enabled for x86_64 and aarch64.

Can we please get CONFIG_SECURITY=y set on the Docker Desktop linuxkit VM as well?

Reproduce

1. Install Docker Desktop (v4.28.0) with kernel 6.6.16-linuxkit on an ARM64 Mac
2. Run docker run -it --rm --privileged --pid=host ubuntu nsenter -t 1 -m -u -n -i sh -c 'cat /proc/config.gz | gunzip | grep CONFIG_SECURITY'

Expected behavior
