command_tester.py: Remove clause for x86-32 Windows that is no longer used
command_tester.py: Remove clause for x86-32 Windows that is no longer used

The Windows 'signal handler' code (which used Vectored Exception
Handling insecurely) was removed a while ago.

We no longer set using_nacl_signal_handler=1 on Windows, so this code
always runs with expected_sigtype = 'normal'.
