Allow using EC-RDSA/streebog in pkcs7 certificates in a similar way
to how it's done in the x509 parser.
This is needed e.g. for loading kernel modules signed with EC-RDSA.

I sent a similar patch to support the SM2/3 algorithm combination, which
happened to conflict with your patch.
https://lkml.org/lkml/2021/6/24/248
If possible and you agree, I will put these two patches in a series and
then resend.
Cheers,
Tianjia
