contrib: osmo-trx: Drop explicit --without-sse

Nowadays we have instruction set runtime detection, so there's no point
in disabling it in the binary, specially because nowadays we run in sse
capable host (despite in the past we didn't and there was no runtime
detection, hence why was it explicitly disabled).
