The references to arch/c6x are obsolete now that the architecture
is gone. Remove them.

The feature lists don't match reality as of v5.10-rc4, update them
accordingly (by features-refresh.sh).

The unicore32 port do not seem maintained for a long time now, there is no
upstream toolchain that can create unicore32 binaries and all the links to
prebuilt toolchains for unicore32 are dead. Even compilers that were
available are not supported by the kernel anymore.
Guenter Roeck says:
I have stopped building unicore32 images since v4.19 since there is no
available compiler that is still supported by the kernel. I am surprised
that support for it has not been removed from the kernel.
Remove unicore32 port.

I was manually editing the arch-support.txt for eBPF-JIT, when I
realized the refresh script [1] has not been run for a while. Let's
fix that, so that the entries are more up-to-date.

Now that the script 'features-refresh.sh' is available, uses this script
to refresh all the arch-support.txt files in place.

A number of architecture ports are obsolete and getting dropped,
so we no longer want to track the respective features.
We already removed the lines for metag and mn10300, this does
the same edits for all the others.
For the remaining 21 architectures, this shows how many are known
to implement each given feature:

This brings SECCOMP_MODE_STRICT and SECCOMP_MODE_FILTER support through
prctl(2) and seccomp(2) to User-mode Linux for i386 and x86_64
subarchitectures.
secure_computing() is called first in handle_syscall() so that the
syscall emulation will be aborted quickly if matching a seccomp rule.
This is inspired from Meredydd Luff's patch
(https://gerrit.chromium.org/gerrit/21425).
