wrapGAppsHook: address some shellcheck suggestions
These should not cause issues in practice but it is good idea to handle them.

* prefix and targetOffset are mandatory, as they are always set by the generic builder.
* wrapPrefixVariables and dontWrapGApps are now defaulting to empty value, as they are not mandatory.
