c11/threads: don't include assert.h if the assert macro is already defined

In the gallium code, the assert() macro could come from either the
system's assert.h file (via c11/threads.h) or from gallium's u_debug.h.
It looks like all known assert.h files unconditionally #undef assert
before defining their own version.  So the assert you get depends on
whether threads.h or u_debug.h was included last.

In the gallium code we really want to use the assert() from u_debug.h
(it behaves better on Windows).  In gallium, c11/threads.h is only
included after u_debug.h in the os_thread.h wrapper.  So Adding
an #ifndef assert test in the threads*.h files avoids using the system's
assert().
