[3/5] kernel32/tests: Ensure VirtualAlloc tests do not depend on previous memory allocations.

[Sebastian Lackner]

Following tests try to allocate memory at (char *)addr1 + 0x1000.
We expect that no memory is mapped at this location.

Patch 5 would let a test marked as todo_wine succeed otherwise.
