sys/prctl.h: add PR_*_TAGGED_ADDR_* from linux v5.4
per thread prctl commands to relax the syscall abi such that top bits
of user pointers are ignored in the kernel. this allows the use of
those bits by hwasan or by mte to color pointers and memory on aarch64:
linux commit 63f0c60379650d82250f22e4cf4137ef3dc4f43d
