osl: fix Pipe noacquire/acquire tests

There is an incomplete test of ::osl::Pipe::Pipe(oslPipe, __sal_NoAcquire),
but the comments show that the tester wasn't able to figure out a way to
test the noacquire variant of this constructor. However, they seem to
have not just given up but copied and pasted the acquire and no acquire
tests - the error codes for the acquire test talk about non-acquisition
and don't actually see if the handle is the same or not.

I have fixed this test. To test if the noacquire is working or not then
you merely have to:

1. create a new Pipe instance
2. create a new Pipe non-acquired instance copy of the first instance
3. delete the non-acquired instance copy
4. try to send a single character to the original Pipe instance, which
   should return an error (negative return result) because at this
   point there is no valid pipe to operate on as the pipe should have
   been destroyed when you deleted the copy.

If the send() succeeds, then this is a test failure.

For the acquire test, it didn't actually test if the handles are the
same - I have corrected this now.
