Cause
=====

After investigation, commit 3c3390532736cfb5198f863d0d2b218e21fcf76d [1]
introduces the test regression.

Albeit [1] removes `LTTNG_SESSIOND_THREAD_HT_CLEANUP` from the `THREAD`
array and the corresponding error message in `ERROR_STRING`, it does not
modify the `NEEDS_ROOT`, `TEST_CONSUMERD` and `TEST_RELAYD` arrays.

Also the test count is not adjusted to reflect the removal of the
`THREAD` element.

Solution
========

Remove the unused data from `NEEDS_ROOT`, `TEST_CONSUMERD` and
`TEST_RELAYD` and adjust the test count.

Known drawbacks
=========

None.
