tests: thread_analyzer: disable QEMU icount

This disables QEMU icount for all the simulated platforms
in the allowed list. With icount enabled, the printout from
the thread analyzer would be continuous and non-stop instead
of the default once every 60 seconds. Besides, the console
harness only needs one, and these is no need to waste CPU
cycles and memory for processing the extra ones.
