Subject: [PATCH] neteq_rtp_fuzzer: limit the fuzzer input size to avoid
 timeout

The length of the fuzzer input can sometimes be really long (more than
600000 bytes), and this take a very long time to execute. Typically,
the fuzzer times out instead. This change limits the used length of
the fuzzer to 100000 bytes.
