kernel32/tests: Add a test for creating named mapping after closing without unmapping.

[Alexander Morozov]

On Wine named mapping exists for other processes after closing mapping 
handle until a process created mapping unmap memory. Second 
CreateFileMapping in this test returns ERROR_ALREADY_EXISTS on Wine. On 
Windows a mapping can not be opened after closing its handle.
