procutil: avoid use of deprecated tempfile.mktemp()

In the previous version, I used tempfile.mktemp() because it seemed to be the
only way to open a file from two processes (the Python documentation says the
file backing NamedTemporaryFile can’t be opened a second time on Windows).
However, it’s possible when passing the O_TEMPORARY flag to the second open.

# A dummy extension that installs an hgweb command that throws an Exception.

from __future__ import absolute_import

def raiseerror(web):
    '''Dummy web command that raises an uncaught Exception.'''

    # Simulate an error after partial response.
    if b'partialresponse' in web.req.qsparams:
        web.res.status = b'200 Script output follows'
