UBUNTU: [Packaging] Add linux-tools-host package for VM host tools

BugLink: http://bugs.launchpad.net/bugs/1764794
OldBugLink: http://bugs.launchpad.net/bugs/1734130

IBM has requested that we package the kvm_stat tool from the
kernel source tree. This is a python script and thus is not
kernel-version specific. Because of this, and in order to avoid
adding a python dependency, this tool is not added to any
existing tools package.

Instead, create a new linux-tools-host package to contain tools
useful on VM hosts which will currently only contain kvm_stat.
Don't build this package unless specified in the architecture
rules file; it should only be built in the master kernel and in
a single architecture for any given series.
