Freeze Break Request: update mock to 2.4-1.fc32.1

In rawhide (and soon f33) systemd sets up a link for resolv.conf file since we are moving to enabling systemd-resolved by default. In mock chroots this is a broken link because systemd isn't actually running there and creating the file it points to. This exposes a bug in mock (or python) where shutil.copy*() ignores the broken symlink and then breaks composes. There is a fix in mock-2.6. Current builders are on mock 2.4. I have a build of 2.4 with just the fix backported. https://koji.fedoraproject.org/koji/taskinfo?taskID=51544202 I'd like to update all the builders to mock-2.4-1.fc32.1 with the fix. This is needed to get rawhide and branched composes happy again. +1s? kevin
