media-libs/libjpeg-turbo: add 3.0.3

Note that while upstream updated their licencing docs in this release
to say there's 2 licences, not 3, they do still say:
> Note that the libjpeg-turbo SIMD source code bears the
> [zlib License](https://opensource.org/licenses/Zlib), but in the context of
> the overall libjpeg API library, the terms of the zlib License are subsumed
> by the terms of the IJG License.

And by our handling of licences, that seems to me like we should still
list the zlib licence.
