Fix getting app resource in split apks

PackageInstallerActivity only considers base APK when showing icon and label
for installing splt apks.
To fix issue, if is installing split apks, uses directory path to
pm.getPackageArchiveInfo, and manual to set the split source pathes via
splitNames of application info.
