The original SELinux support in Docker and Podman does not follow the
default SELinux rules for how label transitions are supposed to be
handled. Containers always switch their user and role to
system_u:system_r, rather then maintain the collers user and role.
For example
unconfined_u:unconfined_r:container_t:s0:c1,c2
Advanced SELinux administrators want to confine users but still allow
them to create containers from their role, but not allow them to launch
a privileged container like spc_t.
This means if a user running as
container_user_u:container_user_r:container_user_t:s0
Ran a container they would get
container_user_u:container_user_r:container_t:s0:c1,c2
If they run a privileged container they would run it with:
container_user_u:container_user_r:container_user_t:s0
If they want to force the label they would get an error
podman run --security-opt label=type:spc_t ...
Should fail. Because the container_user_r can not run with the spc_t.
SELinux rules would also prevent the user from forcing system_u user and
the sytem_r role.

This tool sometimes throws nonsensical or difficult to debug errors.
Verifying DCO and white-space issues in commits has long since been
moved to other tools (github-actions and git pre-commit hooks). There's
no need to duplicate these checks with the git-validation tool.

Moves acquisition of an alternate image provided by the user out of
`acquireVMImage` in `pkg/machine/<hypervisor>/machine.go` and into
`pkg/machine/pull.go` as its own function.

Moves `getDevNullFiles` into a new common file,
`pkg/machine/machine_common.go`, preventing the re-implementation of the
function across the different hypervisor implementations.

We do not use any special netns path for the netns=none case, however
callers that inspect that may still wish to join the netns path directly
without extra work to figure out /proc/$pid/ns/net.

Having hard-coded versions burried under a hidden directory is ripe for
maintenance headaches. Use the latest 'stable' version, since this will
be "close enough" to what we test in CI.

The functions for AppleHV's VM interface implementation (machine.go) had
quite large functions. Pulls out some code that could be moved to its
own function for easier readability and maintainability.

And lo, a miracle occurred. Containerized checkpoint tests are
no longer hanging. Reenable them.
(Followup miracle: tests are still passing, after a year of not
running!)
