MemoryDumpManagerTest.DisableFailingDumpers and 14 other(s) in base_unittests failing on chromium.memory/Linux TSan Tests

Builders failed on: 
- Linux TSan Tests: 
  https://build.chromium.org/p/chromium.memory/builders/Linux%20TSan%20Tests

Looks like access to |dumper_registrations_ignored_for_testing_| is accessed without a lock, and TSan is getting mad about it.
