Some Python scripts fail to set the gettext text domain correctly

When working on !15 (merged) it was noticed that setting the gettext text domain via the TEXTDOMAIN environment variable does not work. At least the following scripts are offenders:

config/chroot_local-includes/usr/local/bin/electrum
config/chroot_local-includes/usr/local/bin/tails-upgrade-frontend-wrapper For an example of how it can be fixed, see 88918f95.
