port brother-mfcj480dw to brother-mfcj470dw

Summary

I have a Brother MFC-J470DW printer and the package was so similar that I was able to adapt the newer MFC-J480DW Solus package to it, and here is the result. I am only moderately familiar with Solus packaging, so bare with me, although I did once-upon-a-time build packages for PISI/Pardus, but I have forgotten all of that by now...

I would love to see if this can work without installing anything to /opt. Would you be willing to try installing the files to ${installdir}/%libdir%, updating the symlinks, and see if it works?

It definitely is doable (as I've pushed a commit which avoids /opt completely that works), but if you want it to completely stay away from /opt you'll have to patch a binary called ImagingArea, as I've done in the latest commit...

The other option would be a symlink in /opt, or just leave it alone.

Not sure how to handle the failed check

Error: Package release is not incremented by 1 (ref: 5020f73acdecb79537da8d5621f7add4e9ca4d31)

It is the first release for this new package, so it shouldn't need to be incremented...
