Merge lp:~kissiel/checkbox/forced-lang into lp:checkbox

[Maciej Kisielewski]

This MR brings an option to build click package with a forced language option.

This will make ignore your language settings on your Ubuntu Device.

To test it run ./build-me --forced-lang=pl_PL or any language you'd like.

[Paul Larson (pwlars)]

It builds ok for me, is there a good way to test it locally or would I need to run it on a real device?

[Po-Hsu Lin (cypressyew)]

Verified this on a Turbo, with locale set to English:

After the following command:
    make build-translations
    ./build-me --forced-lang=pl --install

The Checkbox interface has been changed to Polish as expected.

review: Approve

[Chris Wayne (cwayne)]

LGTM, and since Sam was able to verify it, approving.
