Jon Simons 6252aab88a ecdh: enable ecdh_sha2_nistp{384,521} kex methods
Summary:
Based on Dirkjan's original patch series here:

 * https://www.libssh.org/archive/libssh/2015-08/0000029.html

Here the changes are adapted for the current master
branch, and expanded to include libgcrypt support.

Co-Authored-By: Dirkjan Bussink <d.bussink@gmail.com>
Signed-off-by: Jon Simons <jon@jonsimons.org>
Reviewed-by: Andreas Schneider <asn@cryptomilk.org>

Test Plan:
 * Ran pkd tests for libcrypto and libgcrypt builds.
 * Ran client torture_algorithms.c tests for libcrypto and libgcrypt builds.
 * Tested across multiple libgcrypts ("1.6.3" and "1.7.6-beta").
