linux-headers: add unistd.h
New syscalls are not yet widely distributed. Add them to qemu linux-headers include directory. Update based on v4.3-rc3 kernel headers. Exclude mips for now, which is more problematic due to extra header inclusion and probably unnecessary here. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Michael S.
