fuchsia: Various build fixes for building in Fuchsia tree

- Use "deprecated_system_image" (merging from downstream)
- Add package for crashpad_handler
- Depend on launchpad target instead of a lib when in tree, as launchpad
  is no longer in the sysroot.
- Don't try to remove the -Wexit_time_destructors unless building
  standalone, when it's added by mini_chromiums BUILDCONFIG.gn
