Hi,
What version of LTP suite are you running? I'm assuming it's an older release
since command where you hit the problem has been removed in March:
https://github.com/linux-test-project/ltp/commit/7525e62ea422531610d5cb4ce815e26cc3f6f7ed

Are you running all tests or only a subset (e.g. only syscalls)?
I re-ran syscalls test locally with latest LTP and didn't notice
any owner change.
Assuming some other test is the cause, you could:
1.) setup audit rule to watch for any attribute changes to that file
auditctl -w /opt/ltp/testcases/bin/mknodat01 -k ltpkey1 -p a
(run ltp)
ausearch -k ltpkey1
2.) try to narrow it down by running only subset of tests you run now
