Seccomp filter: deal with arch_prctl(ARCH_CET_STATUS, ...).
The dynamic loader of GNU libc 2.28 uses this system call to
initialize CPU information, see
https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/unix/sysv/linux/x86/cpu-features.c;hb=glibc-2.28#l28.
Simulating an older kernel by returning EINVAL should be the most
harmless rule here.
The ARCH_CET_STATUS symbol isn't yet exposed by the kernel headers;
see the FIXME at the top of
