kmod-static-nodes: don't run if module list is empty

With this kmod commit, modules.devname will be empty by default instead of
containing just a comment:

  https://git.kernel.org/cgit/utils/kernel/kmod/kmod.git/commit/?id=4c30a11d5f

Refine the startup condition of kmod-static-nodes.service to not run needlessly
if the list is empty.
