host-metrics: bind-mount /run/udev for diskio udev lookups 

inputs.diskio (via gopsutil) reads /run/udev/data/b<major>:<minor> to
get per-device tags. Without the mount it falls back to the legacy
/dev/.udev/db/block:<name> path which doesn't exist on systemd hosts,
producing one "stat /dev/.udev/db/block:..." warning per device per
collection cycle.
