Bug#300961: rebuild without libhowl0 dep

[Erinn Clark]

Package: epiphany-browser
Severity: grave
Justification: libhowl0 moving to non-free

(on behalf on RM Steve Langasek)

Please rebuild epiphany-browser without the libhowl0 dependency since it's
moving to non-free. Only a recompile is required, but it's required on
multiple architectures, so there should be a sourceful upload.

Thanks.
