t1509-root-work-tree.sh, which tests behavior of a Git repository located at the root `/` directory, refuses to run if it detects the presence of an existing repository at `/`. This safeguard ensures that it won't clobber a legitimate repository at that location. However, because t1509 does a poor job of cleaning up after itself, it runs afoul of its own safety check on subsequent runs, which makes it painful to run the script repeatedly since each run requires manual cleanup of detritus from the previous run. Address this shortcoming by making t1509 clean up after itself as its last action. This is safe since the script can only make it to this cleanup action if it did not find a legitimate repository at `/` in the first place, so the resources cleaned up here can only have been created by the script itself.

This test requires write access in root. Do not bother if you do not

have a throwaway chroot or VM.

Script t1509/prepare-chroot.sh may help you setup chroot, then you

can chroot in and execute this test from there.
