Subject: [PATCH] codec_ilbc: Disable system ilbc if version >= 3.0.0

Fedora 37 started shipping ilbc 3.0.4 which we don't yet support.
configure.ac now checks the system for "libilbc < 3" instead of
just "libilbc".  If true, the system version of ilbc will be used.
If not, the version included at codecs/ilbc will be used.

Resolves: #84
