Add libdvdnav, libdvdread, libdvdcss and libbluray to buildsystem deps

[Barrett]

• We need to get libdvdnav and libdvdread into the buildpackages for ffmpeg
• It needs to be done for all architectures

IIRC, libdvdcss contains encryption keys that we definitely cannot include in Haiku for legal reasons. Are the others of any use without that?

I added libdvdread, libdvdnav, libbluray to x86_64 in hrev53887. We don't have native gcc2 packages for these on 32-bit. Assuming BuildFeature is used properly, it shouldn't be a big deal (the add-on you're developing just won't be included if the build-packages isn't available.)

Hi pulkomandy, I follow Fedora mainly for legality in software because they have the Red Hat legal team on their side. They have a page on DVD playback (​https://fedoraproject.org/wiki/Multimedia/DVD), and VideoLAN has a page on legal (​https://www.videolan.org/legal.html). From what I understand, libdvdcss does not have encryption keys included, but has a method to extract the keys using the algorithm of CSS. It is a similar issue with libaacs, which only implements the AACS specification and does not include keys. I may be incorrect about libdvdcss, but from what I understand, as long as we are not also publishing software that actively allows for ripping of DVDs to raw format without copy protection, we should be fine, YMMV and all.

This was done a while ago.
