[bug#34324] [PATCH] gnu: artanis: Make some improvements.

[Christopher Baines <mail@cbaines.net>]

* gnu/packages/guile-xyz.scm (artanis): Remove a tab character by the
revision.
[arguments]: Patch the site-dir for the help command, to make it work. Wrap
the art command such that it finds guile-json and guile-redis.
