qpid-proton: disable LTO to fix honggfuzz linking (#9884) 

@astitcher The issue is
https://github.com/google/honggfuzz/issues/336#issuecomment-1458427538,
for some reason the weak symbol from honggfuzz (placeholder function
that prints help message and kills the fuzzer) gets used instead of our
LLVMFuzzerTestOneInput.

I think that disabling LTO is a good temporary fix, to at least get all
the fuzz builds working.
