Use shared k0s build workflow in nighty network conformance runs

This reduces quite some duplicate logic. Remove the ability to test a
specific pull request, to keep things simple. It hasn't been used in a
long time. This way, it doesn't need to be integrated into the shared
build workflow. Also, the network conformance tests are now part of the
standard integration test suite anyway.
