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.
The r and s integer components of the signature can have varying size.
Therefore we do the size checks for the entire signature with a regular
expression that accounts for the varying size. The most typical cases
are supported following hours of running the tests with varying keys.
