[pm] allow debuggable apps to be downgraded on release builds

Browse Source 
By preserving the INSTALL_REQUEST_DOWNGRADE flag throughout the
installation session, we can check whether the app is debuggable and
downgradable at a later stage of the installation during
isDowngradePermitted(). If the app is debuggable and the downgrade has
been requested, the installation should be allowed.
