Wrapper for reading DMI data.
If running in a container return None. This is because DMI data is
assumed to be not useful in a container as it does not represent the
container but rather the host.
This will do the following (returning the first that produces a
result):
1) Use a mapping to translate `key` from dmidecode naming to
sysfs naming and look in /sys/class/dmi/... for a value.
2) Use `key` as a sysfs key directly and look in /sys/class/dmi/...
3) Fall-back to passing `key` to `dmidecode --string`.
If all of the above fail to find a value, None will be returned.
