[asan] Use full binary path in the Android test runner.

Summary

This prevents the confusion when there are similarly named tests in
different configurations (like in test/sanitizer_common).

Thy this is relative to the / and not to maybe build root?

This is more reliable, for example, you may run tests from two build trees on one device at the same time. Also, it is easier to implement - otherwise we would need to pass the build root to the script somehow.
