libvirt-login-shell: New binary package

The virt-login-shell tool is not as commonly used as virsh and
virt-admin, plus it only works locally and has a hard dependency
on the lxc driver, so it makes more sense for it to be in its own
separate binary package.

+ Libvirt is a C toolkit to interact with the virtualization capabilities

+ a long term stable C API for different virtualization mechanisms. It currently
+ supports QEMU, KVM, XEN, OpenVZ, LXC, and VirtualBox.
+ .
+ This package contains the virt-login-shell tool, which can be set as a user's
+ login shell to isolate their sessions using LXC containers.
