description:
SSL: fixed reporting of the detected library version.

Previously, `openssl version` command was used to report the OpenSSL
version.  Whereas, when provided with custom CFLAGS and LDFLAGS the
used library may differ from the system one.

The fix is to report OpenSSL version using the provided library.
