netns test: improve ping test

Browse Source 
- Use fping for pinging multiple hosts in parallel.
  Significantly improves test runtime:
  >13 s -> ~200 ms for the negative ping tests.
- Only test network namespaces that are enabled.
  This allows running the netns test with a reduced service set for debugging.
- Remove deprecated services, instead add btcpayserver, spark-wallet
