upload.py: Fixing exception declaration
upload.py: Fixing exception declaration

Previous code was generating such exception at run-time:

[Mon Jun 10 11:30:14 2013] [error] [client 10.142.18.195] File /usr/lib/cgi-bin/upload.py", line 21 except OSError as e:
[Mon Jun 10 11:30:14 2013] [error] [client 10.142.18.195] SyntaxError: invalid syntax
[Mon Jun 10 11:30:14 2013] [error] [client 10.142.18.195] Premature end of script headers: upload.py
[Mon Jun 10 11:33:02 2013] [error] [client 10.142.18.195] File [client 10.142.18.195] /usr/lib/cgi-bin/upload.py", line  21

I'm not a python expert, I hope the patch is correct, at least, that
doesn't crash anymore
