spec: remove redundant %if

The daemon-driver-{qemu,lxc} packages are only built if
%{with_driver_modules} is specified, so they do not need to
further test this condition.  Likewise, the daemon package
is only built if %{with_libvirtd} is specified, so it does
not need to further test this condition.

* libvirt.spec.in (daemon-driver-qemu, daemon-driver-lxc):
Unconditionally require libvirt-daemon-driver-network.
(daemon): Unconditionally include lock-driver files.
