tests: test_t3_instance_names_no_config disregards tmpdir path length

[themilchenko]

Now test with name test_t3_instance_names_no_config in test/integration/status/test_status.py disregards path of TMPDIR. The test cares about temporary directory that uses test but not about TMPDIR that can be too long.

See the error log that was in MacOS CI for example

When the expected log with right paths length should be look this way

Need to take into account the length of TMPDIR to prevent such unexpected errors.
