On macOS jpackage will print

```
Warning: For signing PKG, you might need to set "Always Trust" for your certificate using "Keychain Access" tool.
```

message when signing a PKG bundle on macOS 10.12+ [1]. This warning is redundant, as the user should have this type of configuration when using jpackage for any signing.

On Windows, jpackage will print

```
WiX <WIX_VER> detected. Enabling advanced cleanup action.
```

notification when using WiX3.6+ for MSI and EXE packaging [2]. This notification is redundant: The oldest officially available version of WiX is 3.11 [3].

Remove these messages.
