Subject: [PATCH] fix: ensure app ENV directory exists at
 DOKKU_LIB_ROOT/config/{app}

The post-create trigger only created the property directory at
DOKKU_LIB_ROOT/config/config/{app}/, but getAppFile() writes the
ENV file to DOKKU_LIB_ROOT/config/{app}/ENV. Add setupAppConfigDir
to create and permission the ENV directory in both post-create and
install triggers, and clean it up on post-delete.
