spec: Rename the libvirt-lock-sanlock subpackage

The new name "libvirt-daemon-plugin-sanlock" provides consistency with the
newly introduced "libvirt-daemon-plugin-lockd" subpackage.

It's also a good opportunity to taking ownership of
%{_libdir}/libvirt/lock-driver/, removing the need for a dependency on the
libvirt-daemon package.
