Revert "test-lib: allow prefixing a custom string before "ok N" etc."

Now that ad0e623 (test-lib: support running tests under valgrind in
parallel, 2013-06-23) has been reverted, this support code has no
users any more.  Revert it, too.

This reverts commit e939e15d241e942662b9f88f6127ab470ab0a0b9.
