package/libebur128: remove package

libebur128 was added to buildroot in July 2016 with commit
a32d29cd84789d7406022c7bb9861e5bda530013 to provide an external
dependency for ffmpeg.

ffmpeg removed this external dependency and switched to an internal
version in November 2016 with upstream commit
http://git.videolan.org/?p=ffmpeg.git;a=commitdiff;h=005d058f4230f3207ebcf1131df7426d4f57392f
which was first included in ffmpeg version 3.3.

Buildroot bumped ffmpeg to version 3.3 in April 2017 with commit
21d93a1351ca8d4e5185c22a81becdaf08a9bdd3 and forgot to remove the
dependency to libebur128.

This went unnoticed until libebur128 fails to build with cmake 4.x.
Upstream saw its last commit four years ago. Instead of fixing an
unused package we removed it from buildroot.
