Make the cluster module intercept the `--debug-port=<port>` command line
switch and replace it with the debug port of the child process.
A happy coincidence of this change is that it finally makes it possible
to run the sequential/test-debug-signal-cluster in parallel, it now no
longer needs the default port numbers.

The test does not work well with concurrent invocations of the test
runner because it uses fixed port numbers. The functionality it tests
is covered by sequential/test-debug-port-cluster, a verbatim copy with
the only difference being that it doesn't use fixed port numbers.
