ENH: delay testing of FOAM_EXT_LIBBIN

- only test in the packages that actually require it.
  State as a requirement.

ENH: skip build of packages with known mingw issues

- primarily kahip and pt-scotch.
  Others may also have issues, but for these we tend to use system
  packages anyhow.

ENH: add '-force' option to various scripts

- overrides some _lazy_ build logic
