Turns out what i needed to do was to override dh_auto_test and
explicitly pass --features=cli, like so in debian/rules:


override_dh_auto_install:
	dh_auto_install -O--buildsystem=cargo -- --features=cli


I'll upload 0.25.0-1 after i have a chance to test it a bit, and of
course it will need to make its way through NEW as well, since the -dev
package isn't in debian yet (i'm using collapse_features=true for this
package to avoid conflict with the ftp-team).
