[PATCHv2 2/1] test_common: eliminate call to non-existent cleanup_task

[Eric Wong]

cleanup_task is long gone since all that cleanup work got moved
into DS itself.  Adding a DS->Reset here breaks t/imapd.t (and
possibly other tests), and is actually unlikely to avoid any
cleanup segfaults on OpenBSD since those are only happening
after `END {}' blocks are called.

 Original 2/1 patch broke t/imapd.t :x
