SCHED_CORE is finally available for ARM64 and ARM.

SCHED_SMT was needed for that.

Refers to #83

Disabling kernel modules is a radical method to cut the kernel attack
surface. It may be useful for some systems.

Quoting CLIP OS recommendation:
```
Disable module loading once systemd has loaded the ones required for the
running machine according to a profile.
```

--kernel-version option will extract the version in /proc/version.
This is especially useful on embedded systems where config.gz doesn't
always contain the kernel version
