Manuel Pégourié-Gonnard cb424097be compat.sh: properly skip unsupported DTLS 1.2 
Skipping DTLS 1.2 with old versions was already done, but now properly
test support only once and use the results.

Note that historically, this script's policy was that it's the user's
job to find the right value of -e (EXCLUDE) for their version for
OpenSSL & config. Now it's a weird mix of that and the script doing some
detection and skipping.
