BOX v4.x support to build PHAR version

[llaville]

Hello,

1. Explains given on https://github.com/tomzx/php-semver-checker#building-php-semver-checkerphar is outdated now with BOX v4.x

The BOX build command was replaced by the compile command.

2. The box.json is now invalid with BOX v4 support. The compactors namespaces are different !

Here is the patch to fix it !
