[PATCH] dix: append "built-ins" to the font path in SetDefaultFontPath

[Rémi Cardona]

49b93df8a3002db7196aa3fc1fd8dca1c12a55d6 made the hard dependency on
a "fixed" font go away but only Xorg could use the built-ins fonts by
default.

With this commit, all DDXs get "built-ins" appended to their FontPath, not
just Xorg.

Tested with Xorg, Xvfb and Xnest.
