sd-device: don't accept non-sysfs paths
There are some file systems mounted below /sys/ that are not actually
sysfs, i.e. are not arranged in a sysfs/kobject style. Let's refuse
those early. (Example, /sys/fs/cgroup/ and similar.)
(Also, let's add an env var for this, so that it can be turned off for
test cases.)
