msacm32/tests: Add more acmStreamPrepareHeader tests

[Bruno Jesus]

Now I understand the problem of
https://bugs.winehq.org/show_bug.cgi?id=24723 (Lost Horizon game
crashing during audio play)
It tries to prepare a buffer with less than block align size, this
gives error in Windows but works in wine and then the game tries to
convert data an crashes.

Also wine64 fails in one test so I added a todo and changed the test
print to hex like the rest of the tests.
