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

Wed Apr 29 23:08:28 CDT 2015

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.

Related to https://bugs.winehq.org/show_bug.cgi?id=38417.
Test failures with "Test failed: attributes of file "testfile.xxx" are 0x0820" are not related to this patch.
