Fix build
Fix build

Composer build phar-file was still problematic, fix is to switch back to
composer.phar from composer-build.phar which is not accepted by the phing
build.

Additionally the build target is now "dist_clean" instead of "dist".

This commit streamlines the build.sh file 100% with N98-Magerun 2.
