hudbars+hbhunger+hbarmor - fix armor bar set to 0% due old loading engines

* for minetest 0.4.16 and 0.4.17 loading of mods is a pain, the
  `on_mods_loaded` still do not exits and only using dependency
  we can get sure a mod its present.
  hudbars need armors parts be present and 100% lodaed to property
  check the armor.def so made optional dependencies only in depends.txt
  cos mod.conf is for newer engines and those works perfectly.
  This only happened at player join or initialization, due
  several errors in the already buggy 3d_armor mod, check:
