Warn the developers if ebuilds install files with xattrs to ${ED}.
The xattrs may or may not be preserved when installing the package,
making them unreliable on one hand, and somewhat suprising in other
cases (e.g. when they unintentionally leak from developer's system).This is the first step towards restoring PMS compliance and *not* preserving extended metadata.
