Hi all,

the Shepherd currently does not build from a clean git repository (on
GuixSD in a shepherd environment), as "autoreconf -ifv" does not create
missing files related to gettext unless the version is specified.

This tiny patch fixes the gettext version and allows bootstrapping to
work from a clean git checkout.

By the way, shouldn't there also be a "./bootstrap" shell script, as is
customary in a lot of projects including Guix?

Cheers,
Florian
