Well, this doesn't really do anything. I'm thinking about something
consuming the libgpiod rust bindings to actually be a useful
replacement for kernel sysfs.

The master plan is: provide a drop-in user-space replacement for
sysfs, make users convert to using it instead of the real thing,
eventually remove sysfs from the kernel and then some time after
remove the compatibility layer from existence forcing everybody to now
move to pure libgpiod. :)
