Fixes to various "gain constant ability" effects

[AMMayberry1]

Fixed a couple of subtle issues related to various effects granting a constant ability to the attached unit.

• The Piloting helper was not correctly adding a zone filter to the gainCondition check, which can result in exceptions happening in some cases
• In several cases we had mis-implemented an ability from an upgrade where it says the attached unit gains a constant ability targeting itself, and were instead using the upgrade as the ability source. This came up during testing for Kazuda since it has implications for how his ability impacts those cards. Should be fixed now.
