[zircon][ulib][zxtest] Swap args in ASSERT_OK to match (expected, actual) order

Change the order of the arguments passed to the underlying
_ASSERT_VAR_STATUS macros so that "expected" comes before
"actual". This matches what we do in the other macros and matches
_ASSERT_VAR_STATUS's "prototype".

Now, when an ASSERT_OK fails, the printed message correctly identifies
the tested argument as "actual".  For example,

    zx_status_t status = ZX_ERR_BAD_STATE;
    EXPECT_OK(ZX_ERR_BAD_STATE);

now yields:

    Expected: ZX_OK
    Actual  : status
    Which is: ZX_ERR_BAD_STATE

Test: Ran exiting integration tests and observed the output
