ioengines: Add thread_data to .errdetails

No functional changes here, but added a 'struct thread_data *td' to the
errdetails callback.  This is a prep patch for the following commits to
access 'td->eo' instance from .errdetails callback.

Bump up FIO_IOOPS_VERSION to 36 since the previous commits updated
.errdetails callback for ioengines by adding 'thread_data' argument.
