Subject: sogrep: do not hardcode the mirror

Use the first mirror that is configured for each repo in pacman.conf.
With the default configuration, this means to use the first mirror from /etc/pacman.d/mirrorlist.

If a repo is not configured in pacman.conf, fall back to https://geo.mirror.pkgbuild.com.
