This test case should cover the variant field now, as we have
add Variant to default value of spec.platform.

The variant is required for platform match while pulling images
for ARM platforms. Currently, the cpuVariant only would be assigned
on linux/arm|arm64 platforms. Other platforms this variable would
be empty. So we can use this cpuVariant to initialize the Variant
field.

In the commit "26329b2b8d7fd4e290b2b0f0163547f2d79bb817",
dmcgowan/fix-pull-multi-arch, PR#1535. The containerd has enabled the pull
multi-arch image support. But the platform.variant field of OCI for ARM
hadn't been ready at that time, so all ARM images could not pull successfully.

In this patch we'll detect the ARM variants from /proc/cpuinfo. Because Linux
kernel has already detected the ABI, ISA and Features for us. We don't need to
parse them from registers again.

On ARM platforms, we have to prepare the variant for spec.platform.
Currently, this action would only work on Linux/ARM system. We
introduce these two helpers to check running system's OS and Arch.

Matching support is now implemented in the platforms package. The
`Parse` function now returns a matcher object that can be used to
match OCI platform specifications. We define this as an interface to
allow the creation of helpers oriented around platform selection.

For supporting selection of images and runtimes in the containerized
world, there is thin support for selecting objects by platform. This
package defines a syntax to display to users that can express specific
platforms in addition to wild cards for matching platforms.
The plan is to extend this to provide support for parsing flag
arguments and displaying platform types for images. This package will
also provide a configurable matcher to allow match of platforms against
arbitrary targets, invariant to the Go compilation.
The internals are based the OCI Image Spec model.
This changeset is being submitted for feedback on the approach before
this gets larger. Specifically, review the unit tests and raise any
concerns.
