std.Thread.setName: use unused code

I noticed a comment saying that the intent of a code's author was unclear.
What happened is that the author forgot to put the check for whether the
thread is the calling thread (`self.getHandle() ==
std.c.pthread_self()`) in the `if (use_pthreads)`.
If the thread is the calling thread, we use `prctl` to set or get the
thread's name and it does not take a thread id because it knows the id
of the thread we're calling `getName` or `setName` from.
I have found a source saying that using `pthread_setname_np` on either the calling thread
or any other thread by thread id would work too (so we don't need to
call `prctl`) but I was not sure if that is the case on all systems
so we keep using `pthread_setname_np` if we have a
specific thread that is not the thread we're calling from, and `prctl`
otherwise.
