Remove unnecessary OpenSSL init and unit commands in unit tests

After the removal of OpenSSL 1.0.2 support these instructions are
no longer needed and the main OpenVPN program also no longer calls
them in init_ssl_lib or free_ssl_lib.

Also remove them from the unit tests. This also solves a
deprecation warning on EVP_cleanup when compiling with aws-lc
