Rule enable_fips_mode doesn't work on s390x architecture

[jan-cerny]

Description of problem:

Rule enable_fips_mode on RHEL 8 checks if the kernel boot parameter is configured for FIPS mode as a part of the OVAL check, but it checks the GRUB 2 configuration, the OVAL test "test_grubenv_fips_mode" reads from /boot/grub2/grubenv, but there is no such file on s390x architecture, because this architecture uses the ZIPL bootloader instead of GRUB 2.
