Wifi: Mark disabled tests with @Ignore

Mark disabled tests so that Errorprone stops complaining about
unannotated test methods.

Cleanup from update to Errorprone 2.2.0, which warns on more
cases, and enforces JUnit4 style (@Ignore + @Test).

(cherry picked from commit 03ba3e6683b20c22d6dd4fb32c93bcaf7858cfa2)

Bug: 72076216
