seccomp additions for glibc 2.33

glibc 2.33+ on these platforms, when used in conjunction with newer
Linux kernels, needs various new syscalls in the seccomp whitelist
(they've been added to allow for post-2038 time).

Patch against 8.4p1 attached.

Ranked major because it builds fine but then fails at connection-accept
time, which can lead to service loss and annoying trips to get a
console (thankfully I only had to make a trip across the room to plug
the serial console in).
