[Debian-on-mobile-maintainers] Bug#1115888: unl0kr: Migrate to new upstream repository

[Travis Wrightsman]

Package: unl0kr
Severity: wishlist

It seems unl0kr has a new upstream repository where development
continues:

https://gitlab.postmarketos.org/postmarketOS/buffybox

Unfortunately unl0kr is now bundled with a bunch of other tools, so I
guess it makes sense for a src:buffybox that provides unl0kr?
