This reverts commit 6a1a4880.

We can't check the PHP version in the installer since base.php already used 5.4 syntax. Thus for a better UX we show a simple warning instead of a fatal PHP error.

There is not much sense in having these files marked executable, we should avoid that.

Log the error instead of potentially leaking sensitive information

At that point the checks are already done before
