use proper quit semantic for openssl s_client

Browse Source 
openssl s_client expect "Q" as the first character on a line,
with case being significant. Also, the \n marker is unnecessary
the echo command prints a newline automatically, additionally,
for the \n to be actually interpreted, the -e option must be used
