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.
