makechrootpkg: Put "keyserver-options auto-key-retrieve" in gpg.conflukeshu/to-upstream/misc-20180115

This allows signature verification by `makepkg --verifysource`, `git
verify-tag`, and such without requiring the user to manually retrieve
the keys first.

This is based off of devtools32 commit 009695b (2017-06-27) by
Erich Eckner <git@eckner.net>.  There are 2 differences from that
commit:
 - In this version, gpg.conf is owned by builduser, not by root
 - In this version, we don't keep appending duplicate lines if we
   re-use a chroot
