parisc: Enable seccomp architecture tracking

stable inclusion
from stable-5.11-rc1
commit 6aa7923c
bugzilla: 167382
CVE: N/A

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=6aa7923c8737d1f8fd2a06154155d68dec646464

-------------------------------------------------

To enable seccomp constant action bitmaps, we need to have a static
mapping to the audit architecture and system call table size. Add these
for parisc.
