kernel-yocto: test for empty artifacts

Browse Source 
With the updated kernel tools, we generate a list of sccs, patches,
configs and BSP definitions as part of the meta data generation.

It is valid if there aren't any of these artifacts found (i.e. you
are just building a branch and a default config), but invoking the
tools with no inputs isn't a good idea.

To avoid this issue, we generate a string based on the artifacts
and skip calling the tools if there's nothing to do.
