Testing Farm is now able to test aarch64 builds. It would be nice if users could add testing of these builds, can be enabled by default. I believe for builds which do not want this would could use tmt context and just report info result ...

In Testing Farm request we need to:

1. set arch field to aarch64
2. set an aarch64 specific compose (with the suffix -aarch64), compose list: https://api.dev.testing-farm.io/v0.1/composes

@mvadkert will try to implement the feature
