[PATCH] kernel32/test: Fix the semaphore handling in test_WaitForJobObject().

[Francois Gouget]

Don't include 'sync ' in the semaphore name because it will end up as a
separate argument in the child process, causing it to not find the
semaphore.
Switch the child to OpenSemaphoreA() to reduce the risk of accidentally
create a new semaphore instead of opening the parent's one.
Use wait_child_process() instead of a raw WaitForSingleObject(). The
timeout is longer but the process is expected to exit immediately
anyway and this allows proper handling of child failures (such as if
there is a bug with the semaphore handling).

The lack of checks and the short 1s timeout that this caused mostly 
masked the issue.
