Fix clang warnings related to OpenSSL 1.x

When CI tests are run locally on machine without OpenSSL 3.0, there are
some warnings during clang-tidy scan. They are related to unsupported
c-style code (implicit bool/int conversion, casting, and varagrs
functions). This change is fixing all of them, without changing
functionality.

Testing done:
- running docker image with UTs on local Ubuntu machine with SSL 1.1 is
  passing all tests, and no clang errors are reported.
