linux: remove xen_dom0 feature entirely

Browse Source 
Xen is now enabled unconditionally on kernels that support it, so the
xen_dom0 feature doesn't do anything.  The isXen attribute will now
produce a deprecation warning and unconditionally return true.
Passing in a custom value for isXen is no longer supported.
