This package is only used by the daemon, so move it to the internal
rootless package instead.
Note that technically this could be in daemon/internal, but as there's
already an existing internal/rootless package (which needs to be in the
top-level internal package because it's also used by /plugin), I'm moving
it there.

This code is currently only used in the daemon, but is also needed in other
places. We should consider moving this code to github.com/moby/sys, so that
BuildKit can also use the same implementation instead of maintaining a fork;
moving it to internal allows us to reuse this code inside the repository, but
does not allow external consumers to depend on it (which we don't want as
it's not a permanent location).
As our code only uses this in linux files, I did not add a stub for other
platforms (but we may decide to do that in the moby/sys repository).
