Filter platform-specific Maven alias targets in E2E tests

Bazel's cquery behavior varies across versions and platforms when handling
Maven dependency aliases. On some combinations (e.g., Ubuntu + Bazel 9.x),
these alias targets appear in cquery output:
- @@rules_jvm_external++maven+maven//:com_google_code_findbugs_jsr305
- @@rules_jvm_external++maven+maven//:com_google_guava_failureaccess
- @@rules_jvm_external++maven+maven//:com_google_guava_listenablefuture
- @@rules_jvm_external+//private/tools/java/.../jar:AddJarManifestEntry

On other combinations (e.g., macOS + Bazel 9.x), these same targets are
omitted from cquery output, with only the actual file targets returned.

To ensure tests pass consistently across all platforms and Bazel versions,
we now filter these unstable alias targets from comparison in E2E tests,
and removed them from the expected results file.

This allows the tests to focus on the stable targets that appear consistently
across all configurations while ignoring the platform/version-specific aliases.
