kernel32/tests: Add tests for deleting readonly files with NtCreateFile.

Wine currently implements DeleteFile based on NtCreateFile with access mask
GENERIC_READ | GENERIC_WRITE | DELETE, but this is wrong. This test shows that
NtCreateFile with FILE_DELETE_ON_CLOSE should also fail without explicitly
requesting read/write access.
