Fix prebuilts of overridden apps

AndroidApp had its own HideFromMake method and flag that shadowed
the one in ModuleBase.  This caused performOverrideMutator to set the
AndroidApp flag, but ModuleBase.skipInstall to read the ModuleBase
flag, resulting in a conflicting install rule being created.  Remove
AndroidApp's HideFromMake in favor of the ModuleBase one.
