Trebuchet : Add live folder removal to removeItemsByPackageName

Previously only removeItemsByComponentName had an entry for live folders
which left removeItemsByPackageName to fall through to regular folders.
This patchset addresses that and marks the folder for removal if the package
was uninstalled.
