[Bug 1103022] [NEW] 70-udev-acl.rules needs to put g+rw on /dev/kvm

[Serge Hallyn]

Public bug reported:

When qemu-system gets installed, the newly installed udev rule causes
/dev/kvm to gets chgrpd to kvm and its mode to get set to g+rw.
However, because /dev/kvm was tagged with ACL previously, there is a
group:: acl on /dev/kvm which does not get removed.  Therefore /dev/kvm
is g+rw in the file mode, but the acl denies group read/write access.
After a reboot all is fine.

I have not seen a clean way to have udev remove that acl, and there is
no reason for it.  So please update the 70-udev-acl.rules file to set
MODE=0660 on /dev/kvm
