support `exception: false'

* ext/socket/socket.c (sock_connect_nonblock):
support `exception: false'
* test/openssl/test_pair.rb (test_connect_accept_nonblock_no_exception):
test `exception: false' on connect,
rename from `test_accept_nonblock_no_exception'
* test/socket/test_nonblock.rb (test_connect_nonblock_no_exception):
new test
