package kit: Add pre-uninstall scripts feature.

Browse Source 
Just like post-install scripts which run shortly after a package is
installed, pre-uninstall scripts are run just before a package is
removed.  Implements enhancement #13427

* Fix script exit code handling vs script launch errors.
* Bump package and repo file version numbers due to new attribute,
  unfortunately makes new .hpkg files not backwards compatible.
* Add pre-uninstall functionality, mostly cloning the post-install
  except in a few places.
* Discover that _RunQueuedScripts() is never called, a future TODO:?
* Update package documentation for pre-uninstall scripts, and use of
  the boot/post-install directory.
