linux-meta update

[Stefan Bader]

Steve Langasek noticed that linux-meta creates a package that depends on
lrm-server which does not exist (lp#214471).
So I prepared a new version that does create lrm-server and while I was
on that I updated the descriptions for openvz and xen which still hat
references to rt. I have heard of this somewhere but I can't remember
where. :(
The new source package would be on chinstrap:~smb/2sign/linux-meta.
Could someone crosscheck and/or sign?

Thanks,
Stefan
