arch: Add parisc architecture support

This patch (v4) adds support for the parisc and parisc64 architectures
to libseccomp.

I didn't split up the patch, because it's pretty trivial.
Those parisc-specific files gets added:
 src/arch-parisc-syscalls.c
 src/arch-parisc.c
 src/arch-parisc.h
 src/arch-parisc64.c

All other changes are trivial because they simply add parisc-specific
case statements in variouse switch statements.

I did ran a "make check" on x86-64 and parisc and all testcases succeeded.
All live testcases succeed as well when running "./regression -T live".

The patch applies cleanly to current libseccomp git head.

Changes between v4 and v3 of this patch:
- Added parisc arch to arch-syscall-check.c and fixup syscall table as
  needed
- Fixed copyright notices in parisc files as suggested by Mike Frysinger

Changes between v3 and v2 of this patch:
- Stripped out patch which reports if a check was skipped because
  valgrind isn't installed.
- Added tuxcall pseudo syscall for 19-sim-missing_syscalls testcase
- Added sysmips pseudo syscall for 29-sim-pseudo_syscall testcase

Changes between v2 and v1 of this patch:
- Enabled seccomp mode 2 regression tests on parisc. Kernel support for
  hppa was added in kernel 4.6-rc1 and backported into the kernel v4.5.2
  stable series.
