Remove build dependencies after docker-php-ext-install #557
Description
Since removing build dependencies after installing PHP extensions (e.g. docker-library/wordpress#267) seems to be a common task it would make sense to have such a functionality in the docker-php-ext-* scripts.

/usr/src/php.tar.xzcan be removed too ?docker run --rm php:7.2.5-cli-alpine3.7 ls -alh /usr/src=> 11.5M (16% of the total image size)J0WI commentedon May 16, 2018
Nope, that is used here.

yes, I mean, once we have installed the dependencies, we could remove it too (not use at run-time).

As for deleting the source, that would be a duplicate of #488.
For auto-removing build dependencies that we add, that is done in the Alpine images:
php/docker-php-ext-install

We don't auto-add build dependencies in Debian since any needed for
phpizeare already installed. See #513 (comment) and #438 for why we don't auto add/remove packages in Debian.As for any other dependencies that could be installed in a Dockerfile, since we didn't add them, we can't reasonably detect that they can be removed.
