Improve reporting for barrier errors

uv_barrier_init() errors are currently ignored.  Use UV_RUNTIME_CHECK()
to catch them and to improve error reporting for any uv_barrier_init()
run-time failures (by augmenting error messages with file/line
information and the error string corresponding to the value returned).
