[chore] remove linux package builds and tests (#34372)

This PR removes the package tests from this repo since they were moved
to the -releases repo in
open-telemetry/opentelemetry-collector-releases#604.

Related issues:
- Original issue:
open-telemetry/opentelemetry-collector-releases#439
- Also fixes
#34748

Advantages of doing this:
- removal of duplicated code that has potential to diverge with linux
package building and testing happening here with custom code, but the
actual code that is used to build the released linux packages is in the
-releases repo. This should result in lower maintenance effort and
removes technical debt.

Disadvantages discussed here:
- bit of a shift-right for the linux package tests since they are now
tested in the -releases repo which could lead to situations where bugs
are found too late and e.g. the contrib repo already got a new tag which
has a bug that only comes up in the releases repo
