[Buildroot] [PATCH 2/2] package/jack2: add missing optional dependencies

[Yann E. MORIN]

jack2 can optionally use opus, readline and eigen3, but those
dependencies were not expressed in out jack2 package, potentially
leading to unreproducible builds.

Add them.

Note that the optinal dependency on celt is not added, because we only
have celt-0.5.1 and jack2 requires celt >= 0.5.2 (even though it does
look for celt >= 0.5.0, it does not build with celt- < 0.5.2). Sinc ewe
can not upgrade celt (for now), we just never make jack2 depend on
celt051, and it won;t find it either, as it just searches for celt.pc
and we have celt051.pc.
