In gettext-base < 1.8.2, like the one we had in Wheezy, gettext.sh references the environment variable ZSH_VERSION, which we do not set. This has prevented us from doing `set -u` in all gettext:ized shell scripts unless we first initialize that variable before sourcing gettext.sh. Now that we install a new enough gettext-base, we can finally do this and remove the initialization hacks. Will-fix: #9371
