Extend the sign_verify test with a pkcs11-specific test.
Since the openssl command line tool now needs to use a key provided by
an engine, extend some command lines with the additional parameters
'--keyform engine'. These parameters are passed using the global variable
OPENSSL_KEYFORM, which is only set when pkcs11 URIs are used.

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

Allow user to set signature's keyid using `--keyid' option. Keyid should
correspond to SKID in certificate, when keyid is calculated using SHA-1
in libimaevm it may mismatch keyid extracted by the kernel from SKID of
certificate (the way public key is presented to the kernel), thus making
signatures not verifiable. This may happen when certificate is using non
SHA-1 SKID (see rfc7093) or just 'unique number' (see rfc5280 4.2.1.2).
As a last resort user may specify arbitrary keyid using the new option.
This commit creates ABI change for libimaevm, because of adding
additional parameter to imaevm_params - newer libimaevm cannot work

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.

when the system has a discrete TPM 1.2 and the user runs the test with a

value because it tries to access TPM 1.2 the sysfs PCRs file and,
