xorg-server.pc: add xserverconfigdir variable

That variable is supposed to be used by drivers to query the path to
the xserver config directory (eg /etc/X11/xorg.conf.d), if they have
to install config snippets. It's supposed to replace / phase-out the
sysconfigdir variable, which has a bit misleading name.
