Set ApplicationInfo (long)versionCode for APEX.

PackageManagerShellCommand defaults to the versionCode contained in
PackageInfo.ApplicationInfo if ApplicationInfo is present. Set
longVersionCode to both PackageInfo and ApplicationInfo, and also change
PackageManagerShellCommand to use longVersionCode instead of the
deprecated versionCode.
