Add PKEY_UNRESTRICTED macro to mman.h and use it in selftests.

For context, this change will also allow for more consistent update of the
Glibc manual [1] which in turn will help with introducing memory protection
keys on AArch64 targets [2].

Applies to 819837584309 (tag: v6.12-rc5).

Note that I couldn't build ppc tests so I would appreciate if someone
could check the 3rd patch. Thank you!
