Podman adds an Error: to every error message. So starting an error
message with "error" ends up being reported to the user as
Error: error ...
This patch removes the stutter.
Also ioutil.ReadFile errors report the Path, so wrapping the err message
with the path causes a stutter.

The Linux implementation uses /proc/stat - the FreeBSD equivalent is
quite different where this information is exposed via sysctl.
