test: use --port=0 in debugger tests that do not have to work on 9229

To avoid failures when there is another running process occupying
the port 9229 which may happen if there is a stale process, use the
--port argument of node-inspect to use a random port in tests that
don't have to work on port 9229.

The following tests are not touched:

- test-debugger-custom-port: tests a specific port
- test-debugger-debug-brk: tests a specific port
- test-debugger-invalid-args: tests other inspect combinations
- test-debugger-pid: node-inspect does not support -p and --port
  together
