[3.6] _ssl_: Fix compiler warning (GH-3559) (#3569)
Cast Py_buffer.len (Py_ssize_t, signed) to size_t (unsigned) to
prevent the following warning:
Modules/_ssl.c:3089:21: warning: comparison between signed and
unsigned integer expressions [-Wsign-compare].
(cherry picked from commit 5a61559fb0776a9a0f08294ec9003cea13940430)
