scripts: sof-qemu-run: update ac30 qemu arguments and mtrace export

Update the QEMU invocation for ACE30 targets (e.g. PTL, WCL) to exactly match the default execution requirements. Remove the redundant `-cpu` argument and export `QEMU_ACE_MTRACE_FILE=/tmp/ace-mtrace.log` into the environment to ensure mailbox and mtrace logs are properly routed and captured by the emulator during simulation.
