[aur-general] Delete request yaourt-abs

[Aliaksandr Stelmachonak]

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
