Add some logic into `wp_tempnam` to prevent it creating 'falsey' directory names that might get used elsewhere within WordPress.
Although this logic looks a little strange at this low level, it's the best location within the Upgrades code for it to happen. Fixes #31811 Built from https://develop.svn.wordpress.org/trunk@31936 git-svn-id: http://core.svn.wordpress.org/trunk@31915 1a063a9b-81f0-0310-95a4-ce76da25c4cd
