Bug#2101: xserver packages fail installation in postinst

[Bill Mitchell <mitchell@mdd.comm.mot.com>]

Package: xserver-svga
Version: 3.1.2
Revision: 2

(and, I'd guess, other xserver packages as well)

The package won't install on a 0.93r6 system without a previous
X11 installation.  It presumes the existence of nonexistent
things, and fails in postinst when they're not found.
