Add Ignore annotation to CrashCheck class

CrashCheck has been broken and always passing for awhile, see
ag/6934559.  As a first step for cleanup we are disabling the class so
that config files can be safely cleaned up.  Then we will continue with
ag/6934559 and other improvements.

Bug: 126760989
Test: Need to build and run .apk locally to prove Ignore is working
