testsuites: tunend: trex: configure.sh: Use trex binary depending on host

gtplab* hosts worked fine with regular t-rex-64 binary, but c240-* and epyc1 segfault when starting it, probably due to use of AVX in the locally compiled binary. On those hosts, use t-rex-64-o binary instead, which doesn't contain such optimizations and hence doesn't segfault.
