This atones^Wfollows up on commit 44469ffd83
which, as its changelog suggests, was not supposed to suck.
* gnu/packages/fonts.scm (font-abattis-cantarell): Update to 0.303.
[source]: Fetch a zipbomb from GNOME's GitLab.
[build-system]: Use the font-build-system. We never actually built
anything.
[arguments]: Add custom 'unpack-source and 'unpack-variable-font phases.
[native-inputs]: Fetch another zipbomb from GNOME's GitLab.
Add unzip to unpack both of them. Remove gettext-minimal.
