Fix nasty bug which resulted in `kata-env` showing `VMContainerCapable = true` even on amd64 systems without virtualisation support (thankfully `kata-check` still showed the correct results). Added arch-specific tests to avoid any possibility of regression. Fixes #660. Signed-off-by: James O. D. Hunt <james.o.hunt@intel.com>
