selftests: drv-net: so_txtime: check IP versions

Browse Source 
This test needs more work, and it fails in non-obvious way
when IPv4 connectivity is not available:

  # Exception| CMD[remote]: /tmp/vjquwblf/gukinuzqso_txtime -4 -c mono -t 1780939014114542914 -S None -D None a,0 -r
  # Exception|   EXIT: -15

Explicitly check for IPv4 support to make the future triage
less painful.
