[2/3] Don't send EXCEPTION_EXECUTE_FAULT to Windows programs that didn't enable DEP. (try 3)

[Michael Karcher]

This is what Windows does, too. If Data Execution Prevention is not enabled
for a process, Windows does not use the EXCEPTION_EXECUTE_FAULT flag, as
the program might be incompatible with it and expect EXCEPTION_READ_FAULT.

This fixes the non-functional single-stepping in Delphi,
as reported for example in
 http://appdb.winehq.org/objectManager.php?sClass=version&iId=22&iTestingId=10795

try3: Use NtQueryInformationProcess to find out whether DEP is enabled.
