Upgrade piglit, compress generated tests

These patches were already on the list in another patchset, the only change is that piglit-generated-tests now RDEPENDS on tar.

Original cover letter follows:

Piglit was removed because the current version was making sdk images too large. This patchset reduces the installed size by 1.5GB and adds piglit back to core-tools-testapps.

Running piglit still requires the same amount of space so in practice this is useful for installed images only.

Thanks,
Jussi
