[archlinux] adjust pkgbuild + add files (#11)

* [archlinux] adjust pkgbuild + add files

We are going to ship the default caddy welcome page on Arch Linux
and we've enhanced the caddy service file with additional security
options.

Note: Arch Linux uses the 'http' user/group for web servers on default.
Therefore we've changed the caddy user/group to 'http' in our service
file.

* bump pkgbuild + add tests
