Revert my previous change.

Apparently it caused `make distcheck` to fail which caused a Bitbucket build pipeline to fail: https://bitbucket.org/pidgin/main/addon/pipelines/home#!/results/%7B9f059724-78b4-4a5e-9780-9a614c7c2742%7D

Not sure how to fix this.

FYI there's a daily cronjob on... rock? in that calls /srv/trac/developer.pidgin.im/mercurial_support/nightly_update.sh which updates https://developer.pidgin.im/l10n/ It's been failing for a few months.
