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.

Hi Tianjia,

few notes below, feel free to completely ignore it.

I'd either put here value openssl-3.0.0-beta1 and pass it to
./tests/install-openssl3.sh or put value as true. Because why define version in
yaml and also in the script? (sooner or later these two will not match).

you should run this only on native build:

         run: [ "$VARIANT" != "cross-compile" ] && openssl version

Also aren't ve interested at the version which is actually being used for
compilation?

Also we don't print this info for Travis CI.

I'd define a variable and use it.
version="openssl-3.0.0-beta1"

Tests heavily use bashisms like [[ ]], which is not a problem when shebang is
/bin/bash. There is no bashism in this script, but be careful to use /bin/sh in
project which contains lots of bashisms.

This is a good way, I will follow you.

It's just to facilitate troubleshooting when CI fails. This is not 
necessary, and it seems useless now, I will delete.

Direct export PATH and LD_LIBRARY_PATH will affect the following 
commands. If add other commands after this code block in the future, it 
will cause potential problems. Of course, this file will not affect it 
now. If you export PATH and LD_LIBRARY_PATH directly in sign_verify.test 
script, there will cause error.
