CLEANUP: threads: remove a few needless includes of hathreads.h
A few files were including it while not needing it (anymore). Some
only required access to the atomic ops and got haproxy/atomic.h in
exchange. Others didn't need it at all. A significant number of
files still include it only for THREAD_LOCAL definition.
