This maintains compatibility between <sys/mman.h> and <linux/uio.h>.
Before that, the addition of process_madvise made those two header

failure in LLDB's Process/Linux/NativeRegisterContextLinux_s390x.cpp
source file.
Fixes commit d19ee3473d68ca0e794f3a8b7677a0983ae1342e
("linux: Add process_madvise").
