Don't crash system process on empty onTuneFailed

This change:
- modifies internal programSelectorFromHal to return null instead of
  throwing NPE on empty input
- throws NPE on two of its usages where null is unexpected
- *does not* throw NPE on one usage where program selector is optional
  (onTuneFailed in RadioModule.java)

Bug: 147522441
Test: boots, but have no quick way to trigger onTuneFailed(Result::error, {})
