Hi, Stefan. Thanks for the patch!
A few comments inline.
Best regards, Ilya Maximets.

There is no need to generate new certificates. There are already
a few pre-generated certificates available in the test directory.
See the OVSDB_CHECK_IDL_SSL_PY on where to find them.
Also, these openssl commands generate unwanted output that is causing
CI failures.

We should also check if python is built with SSL support.
OVSDB_CHECK_IDL_SSL_PY does that by checking if it's possible
to import the library.

It's probably better to pass file names as cmdline arguments like
tests/test-ovsdb.py does. Same can be applied to the C version.
No need for argparse or getopt stuff, just plain args should be
sufficient for now.
Again, see the OVSDB_CHECK_IDL_SSL_PY for the usage example.
