ima-evm-utils: Allow using Streebog hash function

This patch will allow using GOST algorithms from OpenSSL's
gost-engine[1] via config extension (which is the usual way).

[1] https://github.com/gost-engine/engine

Full usage example:

1. Install the gost-engine package for your distro, this could be
libengine-gost-openssl1.1, openssl-gost-engine, or openssl-engines.

2. Edit openssl.cnf appropriately. Reference INSTALL.md of gost-engine
for the detailed instructions.

3. Then GOST algorithms should work:

  $ cp /dev/null a
  $ openssl dgst -streebog256 a
  md_gost12_256(a)= 3f539a213e97c802cc229d474c6aa32a825a360b2a933a949fd925208d9ce1bb
  $ evmctl -v ima_hash -a streebog256 --xattr-user a
  hash: 04123f539a213e97c802cc229d474c6aa32a825a360b2a933a949fd925208d9ce1bb
  $ getfattr -d -m. -ehex a
  # file: a
  user.ima=0x04123f539a213e97c802cc229d474c6aa32a825a360b2a933a949fd925208d9ce1bb
