Add test cases that test the signing and signature verification with the
elliptic curves prime192v1 and prime256v1, also known as NIST P192 and
P256. These curves will soon be supported by Linux. If OpenSSL cannot
generate prime192v1 keys, as is the case on Fedora, where this curve is
not supported, the respective tests will be skipped automatically.

Actually valid sizes are also 0x35 and 0x45 below. Smaller ones seems to
be rather rare, though, but I will leave my tests running. It depends on
the r and s components of the signature and whether they have leading
zeros, which will be cut away.
So I need to send a v2 for this.
