ci: only run USDT interface tests on CirrusCI

As mentioned in #26571, the task running the USDT interface tests
fail when run in docker. cc7335edc87c6ef34429b4df94f53973db520aac
in #25528 added that the tests are run in a **VM** in Cirrus CI.
Running them locally in docker containers might not work:

- We use [bcc] as tracing toolkit which requires the kernel headers
  to compile the BPF bytecode. As docker containers use the hosts
  kernel and don't run their own, there is a potential for mismatches
  between kernel headers available in the container and the host
  kernel. This results in a failure loading the BPF byte code.
- Privilges are required to load the BPF byte code into the kernel.
  Normally, the docker containers aren't run with these.
- We currently use an untrusted third-party PPA to install the
  bpfcc-tools package on Ubuntu 22.04. Using this on a local dev
  system could be a security risk.

To not hinder the ASan + LSan + UBSan part of the CI task, the USDT
tests are disabled on non-CirrusCI runs.
