Update manylinux wheel Docker image and scripts to prepare for BoringSSL support

Need to update manylinux wheel docker images and build scripts to handle changes needed for using BoringSSL instead of OpenSSL for the Python SDK.

NOTE: Until the changes are merged into the C++ SDK, will need to work from PR (draft PR 445). Changes will go under review once the path forward for testing the changes w/in the C++ SDK are more clearly defined. Might also depend on clear path forward for Black Duck scanning w.r.t. BoringSSL. However, that should be a quick change to the manylinux wheel scripts once the change has been merged.
