Augustin Cavalier b24cc7ca75 pthread: Use 1 for PTHREAD_BARRIER_SERIAL_THREAD.
pthread_barrier_wait can return errors, which on Haiku are negative
and so -1 is an error condition, it should not be reused for a magic
constant.

This breaks ABI. However, until the recent fixes, barriers were so broken
that I doubt any application was using them seriously (Mesa, for instance,
has them disabled.)
