* Fixes alien embryo runtime (#71670)
## About The Pull Request
`organ/internal/body_egg/on_life()` -> `organ/egg_process()` -> owner
gets deleted from being gibbed ->
`organ/internal/body_egg/alien_embryo/on_life()`
The owner gets gibbed from the parent call of `on_life()`, which the
embryo does not account for.
Simply adds a check that the owner hasn't been gibbed yet before doing
any life effects.
## Why It's Good For The Game
This runtime didn't even cause any ill effects, but might as well strike
it
## Changelog
🆑 Melbert
fix: Fixed a runtime from alien larva processing after they've gibbed
their host.
