androiddeployqt: Add the missing return value check

The check doesn't affect the flow, since the same check fails the
androiddeployqt execution later, when resolving all elf dependencies.
Skipping the dependency from xml at earlier stage will allow to continue
deployment procedure, without the missing plugins and their dependencies.
