The libfprint master branch will soon contain the v2 API. So change to
use the libfprint-1-0 which will mean that the CI will continue to work.
Note that the build_stable target will need to be removed when the new
libfprint version reaches fedora rawhide.
The gettext in fprintd would be getting confused by a new file in
libfprint that looks like it should have been translated. Ignore this
file in our build.
