fix(cros-kernel2.eclass): Disable OUTOFTREE_BUILD when src is dirty.

Browse Source 
If OUTOFTREE_BUILD=1 (currently disabled but that will change) the
kernel will use the existing checkout as the source tree rather than
cloning another tree. If someone built anything in that tree and .config
exists the build will fail complaining that the source isn't clean.
Instead of failing just disable OUTOFTREE and emit a warning.

OUTOFTREE combined with INCREMENTAL makes successive kernel builds
pretty much no-ops (just re-linking modules and bzImage).
