Disable logging to /dev/xconsole.

The default rsyslog configuration on Ubuntu attempts to open
/dev/xconsole if it exists, and logs an error if it doesn't (which
it normally won't on a headless server anyway). This change installs
a modified configuration with the xconsole-related lines commented
out. This configuration file is valid at least on Ubuntu Oneiric,
Precise and Quantal, which covers the releases we currently use.
