PackageUtil: don't collect certs if package doesn't exist

If packageParser.parsePackage() returns null, don't attempt call
packageParser.collectCertificates().

This fixes a NPE triggered by the following command:

am start -a android.intent.action.VIEW -d file:///blah/blah.apk -t application/vnd.android.package-archive
