od-unix: enable threaded CPU support

Match the Windows target by enabling the shared threaded CPU path on
Unix. The port already provides pthread-backed uae_thread_id and
semaphore helpers, but sysconfig.h did not expose WITH_THREADED_CPU.
That left upstream code that clears cpu_thread_tid after m68k_run()
unbuildable on Ubuntu.

Enable the feature in the Unix sysconfig instead of hiding the shared
code behind extra guards.
