Do not exit if package.format is unset

Both git-package(1) and git-sign-for-cgit(1) set 'errexit', making the
shell exit immediately upon an error. Since git-config(1) exits with an
error if a configuration entry could not be found, a missing entry for
package.format would lead to both scripts bailing out.

We want to fall back to the "tar.gz" format if package.format is unset,
so make sure to ignore this particular error.
