prctl: Disable prctl(PR_SET_MDWE) on parisc
[ Upstream commit 793838138c157d4c49f4fb744b170747e3dabf58 ]
systemd-254 tries to use prctl(PR_SET_MDWE) for it's MemoryDenyWriteExecute
functionality, but fails on parisc which still needs executable stacks in
certain combinations of gcc/glibc/kernel.
Disable prctl(PR_SET_MDWE) by returning -EINVAL for now on parisc, until
userspace has catched up.
