RT3065: ec_private_key_dont_crash

This change saves several EC routines from crashing when an EC_KEY is
missing a public key. The public key is optional in the EC private key
format and, without this patch, running the following through `openssl
ec` causes a crash:

-----BEGIN EC PRIVATE KEY-----

-----END EC PRIVATE KEY-----

(cherry picked from commit b391570bdeb386d4fd325917c248d593d3c43930)
