[PATCH xserver] man: add missing __datadir__ for Xserver XWin man pages

[Gaetan Nadon]

The man pages display __datadir__/fonts/X11/... because __datadir__
is misisng in cpprules.in. Problem was introduced in commit:
b54bc14ce0ae38c4863794bc3096ca86cdb23908
when replacing __projectroot__ in the previous font path.
