sci-libs/pastix: add 6.0.3, masked

The ebuild in principle works but there are several features which for
various reasons remain problematic (see the package.use.mask entry), and
with this being a new major version chances are not all revdeps will be
happy with it (hence the overall mask). Testing very much encouraged!
