[ci-scan] Skip DnsGetHostAddresses/Entry_LocalhostSubdomain_RespectsAddressFamily on Android (refs #128371)

[github-actions]

Reasoning

Android resolvers return IPv6 addresses (e.g. fe80::dc30:2cff:feca:33f4%47) when AddressFamily.InterNetwork is explicitly requested via Dns.GetHostAddresses("test.localhost", AddressFamily.InterNetwork). The Assert.All() then fails because the returned addresses have AddressFamily.InterNetworkV6 instead of the expected InterNetwork. This is an Android resolver behavior difference, not a product bug in System.Net.NameResolution.

Linked KBE: dotnet#128371

Match verification (from Step 4.8):

1. Same test/family: yes — both DnsGetHostAddresses_LocalhostSubdomain_RespectsAddressFamily and DnsGetHostEntry_LocalhostSubdomain_RespectsAddressFamily match the KBE
2. Same failure signature: yes — Assert.All() Failure with Values differ Expected: InterNetwork Actual: InterNetworkV6
3. Same OS: yes — Android
4. Same architecture: yes — arm64 (also x64 via NativeAOT leg)

Impact on platforms

• runtime-extra-platforms / android-arm64 Release AllSubsets_CoreCLR @ windows.11.amd64.android.open — exit code 1
• runtime-extra-platforms / android-arm64 Release NativeAOT @ windows.11.amd64.android.open — exit code 1
