ci: Update linux arm clang reference output (#4782)

Two PRs crossed paths in flight last week -- one adding the ARM tests,
the other doing something that changed the reference output of this test
slightly. Both passed on their own, but the combo left one platform's
output needing the update.

Also, edit nicknames of two tests, they were not unique.
