Revert "test: wait for loop device to be removed"

This reverts commit 1a0e065e9f154f46fd68cd45f46310bc7df7a51c.

This does not work as expected.

After `losetup --detach`, the kernel lazily removes the loop device.
But, systemd-dissect should gracefully handle that. If it does not, then
it is a bug in systemd-dissect.
Let's not hide the real issue in systemd-dissect.
