ssl-opt.sh: Remove wrong test exercising MTU implications of MFL

Browse source 
The negotiated MFL is always the one suggested by the client, even
if the server has a smaller MFL configured locally. Hence, in the test
where the client asks for an MFL of 4096 bytes while the server locally
has an MFL of 512 bytes configured, the client will still send datagrams
of up to ~4K size.

# Mbed TLS will never send datagrams larger than MFL + { Max record expansion },

# The next test checks that no datagrams significantly larger than the
# negotiated MFL are sent.
