[GWP-ASan] Use functions in backtrace test, not line numbers.
There's no unwinding functionality on Android that allows for line
numbers to be retrieved in-process. As a result, we can't have
this backtrace test run on Android.
Cleanup the test to use optnone functions instead, which is more stable
than line numbers anyway.
