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

With this commit, Xprt gets "built-ins" appended to its FontPath.
Fixes the "could not open default font 'fixed'" problem; required now
that libxfont 1.4 does not support Xprint.

Adapted from xserver-xorg commit f56cbe1ef24415d0142b9a7d0ab0a031069ccb52
