Fix lambda TypeError in ptfhost_utils (#5845)

What is the motivation for this PR? Fix the issue reported in #4867, failures: TypeError: () takes exactly 2 arguments (1 given) The fix in #5605 still uses lambda which is not easy to read and may have compatibility issue. How did you do it? Use for loop and concentrate string together and append them to a list. How did you verify/test it? run tests/test_qos_sai.py Signed-off-by: Zhaohui Sun <[email protected]>
