[ci-scan] Skip SocketBlockingModeTransitionTests.ConnectAsync_WithBuffer_Succeeds on Android (refs #128141)

[github-actions]

Reasoning

The test ConnectAsync_WithBuffer_Succeeds consistently fails on Android because IsSocketNonBlocking returns True after ConnectAsync with a buffer completes, while the test expects False. The test already has Android-specific logic (line 227) but the condition does not cover this case correctly.

The [ActiveIssue] attribute is the right fix because it narrows the skip to Android only, matching the observed failure scope.

Linked KBE: #128141

Match verification (from Step 4.8):

1. Same test/family: yes — SocketBlockingModeTransitionTests.ConnectAsync_WithBuffer_Succeeds matches exactly
2. Same failure signature: yes — Assert.False() Failure on the IsSocketNonBlocking check
3. Same OS: yes — Android
4. Same architecture: yes — arm64 (android-arm64 Release AllSubsets_CoreCLR)

Impact on platforms

• runtime-extra-platforms / android-arm64 Release AllSubsets_CoreCLR / Windows.11.Amd64.Android.Open / exit code 1
