lvm/dm/md: switch from lockfiles to $sys/$devpath/holders/*

Browse Source 
This is a more sane solution, than ignoring subsequent "change" events.

The only danger is that we could loop, if a lvm scan triggers a broken
md partition, which triggers a broken PV and so on.

Better fix the scanning tools, not to emit change events for devices,
if no action was taken.
