Keep in sync with the kernel IMA, IMA signature tool supports SM2/3
algorithm combination. Because in the current version of OpenSSL 1.1.1,
the SM2 algorithm and the public key using the EC algorithm share the
same ID 'EVP_PKEY_EC', and the specific algorithm can only be
distinguished by the curve name used. This patch supports this feature.
Secondly, the openssl 1.1.1 tool does not fully support the signature
of SM2/3 algorithm combination, so the openssl3 tool is used in the
test case, and there is no this problem with directly calling the
openssl 1.1.1 API in evmctl.

Allow to have certificate appended to the private key of `--key'
specified (PEM) file (for v2 signing) to facilitate reading of keyid
from the associated cert. This will allow users to have private and
public key as a single file and avoid the need of manually specifying
keyid. There is no check that public key form the cert matches
associated private key.

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.
