Arnout Vandecappelle (Essensium/Mind) e5594f7239 package/dhcpcd: cherry-pick upstream arch-specific privsep fixes
dhcpcd includes privsep-linux.c which contains platform-specific
definitions for the seccomp fixes. A lot of our architectures were not
supported yet in the 9.4.0 release, but are supported now thanks to
Fabrice Fontaine.

Cherry-pick those patches. All of them affect the same code, but they
are cherry-picked individually to keep the correspondence with upstream.
Slight adjustments had to be made but there were no merge conflicts.
