build: Fix JUnit4TestNotRun errorprone warning

The `chrome_junit_sig` build speed benchmark was failing static analysis
due to an errorprone `JUnit4TestNotRun` warning. This was caused by
adding a public method to a test class without a `@Test` annotation.

This change fixes the warning by adding `@org.junit.Ignore` to the
injected method signature.

Additionally, `timeall.py` is updated to run the non-server build first
in debug mode. This ensures static analysis checks are run, catching
these types of issues earlier.
