wayland-native: disable unused macro checks to fix build issue on Centos5.x
We only build wayland-native for the scanner, so disable the bits we
don't actually need. This avoid build issue on older distro such as
Centos 5.x:
| error: 'O_CLOEXEC' undeclared (first use in this function)
| error: sys/timerfd.h: No such file or directory
| error: 'CLOCK_MONOTONIC' undeclared (first use in this function)
| error: 'TFD_CLOEXEC' undeclared (first use in this function)
| error: 'SFD_CLOEXEC' undeclared (first use in this function)
