Use config_netowrkLocationProviderPackageName and
config_geocodeProviderPackageName as intial packages. If another
package exists (or is later installed) that also implements a
provider, and has the same signatures as the original providers,
and has a hgiher version number, then use that instead.
The old code used a funky fix of package name substring checks
and service checks that was broken and not upgradeable.
