Run go test in CI

[tomleb]

Issue rancher/rancher#44474

The test script is not running in the ci script.

The changes:

• Run the test script in the ci script
• Move dapper image to v0.6.0 as that is the latest image (2 years old). The 1.11.2 version is 7 years old according to docker hub.

I have dropped the following changes:

• The git command added allows users on linux to run dapper with DAPPER_MODE=bind which makes builds a bit faster by not requiring the repository to be copied, a bind mount can be used instead.
  • I'm not sure that's the proper way to fix this, need more investigation from me.
• Add volumes for caching go modules. This also makes the build faster.
  • This caching might work differently on GHA so instead of making it work both here and later, I'll defer to when we migrate to GHA.
• Run CI on arm64 in drone: Let's not add anything in drone unless necessary.

I have also changed the order of script called in script/ci.
