[aur-requests] [PRQ#22115] Orphan Request for rssguard-git

gbr [1] filed an orphan request for rssguard-git [2]: Upstream renamed the project file from rssguard.pro to build.pro in June 2019 [1], so this package haven't been building for more than a year now. If possible, I'd like to take ownership of this package. Thanks [1] https://github.com/martinrotter/rssguard/commits/master/build.pro [1] https://aur.archlinux.org/account/gbr/ [2] https://aur.archlinux.org/pkgbase/rssguard-git/
