Gilles Peskine 735ac3ec05 Fix builds with secp224k1 as the only curve
Normally, if an elliptic curve is enabled in the legacy API then it's also
enabled in the PSA API. In particular, if the legacy API has at least one
curve then that curve also works with PSA. There is an exception with
secp224k1 which PSA does not support. In a build with secp224k1 as the only
legacy curve, MBEDTLS_PK_HAVE_ECC_KEYS is enabled (because you can use the
curve through PK) but PSA does not support any elliptic curve, so we can't
run PK-PSA bridge tests.
