Subject: [PATCH 1/2] Skip IPv6 dual-mode socket tests on Android (refs
 #127565)

IPv6 loopback (::1) connectivity is not available in the Android
emulator environment. This causes DualMode connect tests and the
ConnectAsync_WithBuffer_Succeeds test to fail with Connection refused
or unexpected socket state.
