DPP: Fix test functionality for invalid keys with OpenSSL 1.1.0

Browse Source 
It looks like at least OpenSSL 1.1.0i includes the extra checks in
EC_POINT_set_affine_coordinates_GFp() that break the previously used
mechanism for generating invalid keys. Fix this by using the alternative
design that was used with OpenSSL 1.1.1 and BoringSSL.
