xenserver: Only register xsconsole plugin if OVS is running

The 5.6.0 XenServer release will include OVS but not have it enabled by
default.  By only registering the xsconsole plugin on systems running OVS,
this plugin can be included in the main distribution.

Based on commit 0ebd737 from the xs5.7 branch written by Ian Campbell.
