Make regular kernel build artifacts available for download
Browse files Browse the repository at this point in the history 
* artifact zip file contains:
  * zstd compressed build log
  * zstd compressed tarball of kernel images and modules
  * `SHA256` with hash values of the files above
* retention time is 2 days

> **NOTICE:** Unfortunately only registered users can download artifacts
> (GH limitation). Linux 4.19 and 5.4 do not support the `dir-pkg` make
> target, so no artifacts for those, yet.
