Add dependency licenses to about_os_credits.html

Golang binaries are static, but the dependency licenses are omitted by
the build process in most cases. Declaring the transitive licenses in
the ebuild convinces chromite to scan the package's source for license
files: since these projects vendor their dependencies, this means that
about_os_config.html will gain dependency licenses.

To make this work for cri-tools, this switches cri-tools-1.19.0 from
using a binary release to building from source.
