[PATCH xserver 09/10] meson: Get close to parity with autotools for CLIENTIDS tracking.

[Eric Anholt]

The client ID is only needed for XRes, and autotools build ignores the
--clientids= arg if xres is disabled.  We haven't made a meson option
for disabling tracking client ids (is it actually worth a build
option?), so just make this depend on xres.
