x32: fix decoding of mprotect and pkey_mprotect syscall arguments

As there are no compat versions of mprotect or pkey_mprotect syscalls
in x32 personality, "addr", "len", and "prot" syscall arguments have
kernel_ulong_t type and should be printed accordingly.

* mem.c (do_mprotect): Retrieve 1st, 2nd and 3rd arguments using
getarg_klu, print them using printaddr_klu, PRI_klu format,
and printflags64, correspondingly.
