deps: add -no_rand_screen to openssl s_client
Browse files Browse the repository at this point in the history
In openssl s_client on Windows, RAND_screen() is invoked to initialize
random state but it takes several seconds in each connection.
This added -no_rand_screen to openssl s_client on Windows to skip
RAND_screen() and gets a better performance in the unit test of
test-tls-server-verify.
Do not enable this except to use in the unit test.

(cherry picked from commit 9f0f7c3)
