crypto: ecdsa - Drop unused test vector elements

The ECDSA test vectors contain "params", "param_len" and "algo" elements
even though ecdsa.c doesn't make any use of them.  The only algorithm
implementation using those elements is ecrdsa.c.

Drop the unused test vector elements.

For the curious, "params" is an ASN.1 SEQUENCE of OID_id_ecPublicKey
and a second OID identifying the curve.  For example:

    "\x30\x13\x06\x07\x2a\x86\x48\xce\x3d\x02\x01\x06\x08\x2a\x86\x48"
    "\xce\x3d\x03\x01\x01"

... decodes to:

    SEQUENCE (OID_id_ecPublicKey, OID_id_prime192v1)

The curve OIDs used in those "params" elements are unsurprisingly:

    OID_id_prime192v1 (2a8648ce3d030101)
    OID_id_prime256v1 (2a8648ce3d030107)
    OID_id_ansip384r1 (2b81040022)
    OID_id_ansip521r1 (2b81040023)

Those are just different names for secp192r1, secp256r1, secp384r1 and
secp521r1, respectively, per RFC 8422 appendix A:
https://www.rfc-editor.org/rfc/rfc8422#appendix-A

The entries for secp384r1 and secp521r1 curves contain a useful code
comment calling out the curve and hash.  Add analogous code comments
to secp192r1 and secp256r1 curve entries.
