Message about signing dir ownership can cause backtrace

[Donagh McCabe]

This was mentioned in Bug #1180998, but probably overlooked, so I'm creating it's own bug report.

When starting Swift as sudo, I frequently get a failure of this test in auth_token.py:

    if os.stat(self.signing_dirname).st_uid != os.getuid():

(even though the directory is owned by swift)

However, the message logged uses this code:

    LOG.warning(
        'signing_dir is not owned by %s' % os.getlogin())

Notice, os.getlogin() -- not os.getiod() -- is called. This fails with a permission denied; instead of logging a message, the proxy-server is killed.
