build.py: Ensure shared work siginfo files are written to the correct location

Right now shared work signature data is saved to the non-shared directory
which is confusing to everyone including bitbake. Whilst its messy,
extra the stampbase data instead, which ensures the sig data is written
to the correct location alongside its corresponding stamp file.

world-image: add extra target

* similar to world target, but collects all PACKAGES
* recipes marked with EXCLUDE_FROM_WORLD are excluded from world as well
  as world-image
* recipes marked with EXCLUDE_FROM_WORLD_IMAGE are excluded completely
  from world-image, sometimes you can build 2 recipes in same sysroot,
  but cannot install them in the same image
* PACKAGES listed in EXCLUDE_PACKAGES_FROM_WORLD_IMAGE are also
  excluded. You can remove e.g. ${PN}-dbg, but keep all other PACKAGES.
