Do not sanitize the host JNI library

Sanitization currently makes this library reference symbols which
cannot be resolved at runtime without additional magic when starting
the JVM.

Disable this until we can find a fix. This currently fails with:
libconscrypt_openjdk_jni.so: undefined symbol: __asan_option_detect_stack_use_after_return
