test: add secp224k1 check in crypto-dh-stateless

This commit adds a check to test-crypto-dh-statless to avoid an error if
the curve secp224k1 is not present. This could occur if node was
configured with shared-openssl.

The use case for this was building on RHEL 8.1 which only has the
following curves:
$ openssl ecparam -list_curves
secp224r1 : NIST/SECG curve over a 224 bit prime field
secp256k1 : SECG curve over a 256 bit prime field
secp384r1 : NIST/SECG curve over a 384 bit prime field
secp521r1 : NIST/SECG curve over a 521 bit prime field
prime256v1: X9.62/SECG curve over a 256 bit prime field
