Remove broken --test_verbose_timeout_warnings option

On recent Bazel version this option is erroneously reporting every
cached tests result with "excluding execution overhead", e.g.:

  //Documentation:check_licenses             (cached) PASSED in 0.2s
  WARNING: //Documentation:check_licenses: Test execution time
  (0.2s excluding execution overhead) outside of range for MODERATE
  tests. Consider setting timeout="short" or size="small".

See this upstream issue for more details: [1].

Remove this option for now, as it's messing up the test results, and
consider to enable it later when upstream issue is fixed and new bazel
version is released.
