This aligns with strace, and is very useful when tracing multi-threaded
programs. The result is the same in single-threaded programs.
See also "-D log.%d -d tid -strace" which will split the output into per-tid
files.
gettid() requires the _GNU_SOURCE feature test macro, so it might be
unavailable in rare cases. I don't expect it to be a problem though,
because it's implemented by both glibc and musl.

Probably better as qemu_get_thread_id(), but otherwise
Or, without the syscall,
get_task_state(env_cpu(env))->ts_tid
Queued with this change.
