init: Run vendor-specific init hooks on post-fs 



* On <= lineage-16.0 vendor init props were loaded
  during load_system_props() that was called on
  post-fs. This change restores the old behavior,
  which coincidentally allows us to read files in
  /dev/block/* (and probably more) during boot time.
