recipetool: ignore incidental kernel module source

If the source tree happens to contain a kernel module as an example, a
test or under a "contrib" directory then we shouldn't be picking it up
and making the determination that the entire thing is a kernel module.

An example that triggered this is zstd, which ships a kernel module
under contrib/linux-kernel:
