Olivier Gayot b7fb911428 tests: replace use of ssl.wrap_socket that throws warnings in Python 3.10
The function ssl.wrap_socket() is deprecated starting Python 3.7 because
it does not support hostname matching (which is considered insecure). In
Python 3.10, the function now throws warnings at runtime, which makes
Ubuntu / Debian autopkgtest fail.

The function ssl.SSLContext.wrap_socket comes in as the replacement and
has support for SNI and hostname matching.

Replaced all uses of ssl.wrap_socket() by equivalent using
ssl.SSLContext.wrap_socket().
