Better PHP dev-env init (#624)

* Extract logic to avoid adding composer in the path multiple times and add Symfony

* Add missing usage

* Use the official script to install Symfony installer

* Use AUR package

* Move PHP and Composer install in function to avoid duplication.

* Add explicit usage for symfony-cli
