bpo-45328: Avoid failure in OSs without TCP_NODELAY support (GH-28646) (GH-28771)

Operating systems without support for TCP_NODELAY will raise an OSError
when trying to set the socket option, but the show can still go on.
(cherry picked from commit 0571b934f5)

Fixed :class:`http.client.HTTPConnection` to work properly in OSs that don't support the ``TCP_NODELAY`` socket option.
