BUILD: ssl: disable the TLS1.3 session timeout clamp on wolfSSL

wolfSSL's OpenSSL compat layer declares wolfSSL_get_SSL_CTX() (aka
SSL_get_SSL_CTX()) taking a non-const WOLFSSL*, unlike OpenSSL's
const-correct SSL_get_SSL_CTX(const SSL *ssl). Calling it from
ssl_sock_infocbk(), which only has a const SSL *, fails the build:

  src/ssl_sock.c:1772:60: error: passing 'const SSL *' (aka 'const
  struct WOLFSSL *') to parameter of type 'WOLFSSL *' (aka 'struct
  WOLFSSL *') discards qualifiers
  [-Werror,-Wincompatible-pointer-types-discards-qualifiers]

Beyond the build failure, the clamp itself doesn't appear to behave
correctly against wolfSSL's TLS1.3 session/ticket handling, so skip
the whole thing on wolfSSL builds instead of only working around the
compile error.

renewals")
