Both core-pkey.c and ptrace-pkey.c tests have similar macro definitions, move them to "pkeys.h" and remove the macro definitions from the C file.

We could remove this as well right. Since pkeys.h already has this permission defines i.e. PKEY_DISABLE_[ACCESS|WRITE|EXECUTE]

Same here. This can be cleaned up, no? Since pkeys already has this defined.
