[sr-dev] [kamailio/kamailio] WIP app_python3: need a test for a real child process (PR #3139)

app_python3 needs to call `PyOS_AfterFork_Child()`/`PyOS_AfterFork()`
in real child processes.

We need a test for this: rank > 0 may not be sufficient due to
non-forking mode. This POC uses getpid().

#### Description
<!-- Describe your changes in detail -->
@miconda @henningw : this PR is for discussion only: in KEMI Python there is an interpreter function that needs to be called after `fork()` in real child processes. I realise that `rank > 0` may not be a completely correct test as kamailio has a non-forking mode. Your comments would be appreciated.

This POC uses `getpid()` to detect a &ldquo;real&rdquo; child process.
