foreign-kernels: Rewrite scripts to only build one local image

Browse Source 
The scripts used to scrape the various repositories to build
and push package for all foreign kernels. They were designed
to be run periodically and provide "official" foreign kernel
packages. Needless to say we did not run them periodically
and the linuxkit packages became out-dated quickly.

Now, we just provide users who are interested in using foreign
kernels the means to build their own package from specific
vendor kernels.

Each script uses slightly different command line arguments
as the location and naming of the kernel packages differ
wildly. The help message provide a working example which
has been tested with a minimal LinuxKit YAML file.
