Fix CI build issues

MRs created for phosphor-user-manager are failing with below error

```
yaml.scanner.ScannerError: while scanning for the next token
found character '\t' that cannot start any token
  in "<unicode string>", line 21, column 62:
     ... fier-naming.ClassCase,                 value: CamelCase  }
                                         ^
    clang_tidy - FAILED

```
To fix this modified the .clang-tidy file as suggested by CI
