[JENKINS-19636] Allow wildcards for App file path (.ipa, .apk) and Sym path

I needed https://issues.jenkins-ci.org/browse/JENKINS-19636 resolved locally, so I made a quick-fix to do it. I've tested this and it works for me.

One part I don't understand is the intricacies of getFileLocally(). If I need that in some way, feel free to let me know how and I can try to incorporate it.
