jpegenc: Fix getcaps function

When creating the caps allowed to upstream using downstream
restrictions, use gst_pad_get_allowed_caps as that has the
usable formats and puts into it the width, height and framerate
fields. This avoids getting errors about getcaps returning
non subset caps of its pad template.

This error showed up on the metadata plugin unit test in -bad.
