Add Gitlab Runner configuration

Arch Linux is setting up a Gitlab instance.  This adds CI for the pacman
project, testing a range of configurations on Arch and basic builds on
Fedora and Debian.

Note that asciidoc is specifically not installed on the Debian run because
it is all sorts of broken...  Also, the defaults have been set to meson, with
two autotools tests that will soon be removed.
