[aur-general] Delete request yaourt-abs

Please remove the yaourt-abs package: https://aur.archlinux.org/packages/yaourt-abs/ I forked original yaourt to use abs long time ago, when it had issues with accesing packages source code for rebuilding via yaourt -Sb. After yaourt fixed the issue, it is not under development anymore and do not have any advantages over original yaourt. So I think it can be deleted. Thanks, Alex
