fix: move cross-compile vars from global to user-host scope in test subprojects

demo, test-startup, test-compiler-runtime, test-compiler had
MULLE_CRAFT_PLATFORMS=windows in environment-global.sh causing
CI to attempt cross-compilation which fails (no windows toolchain
on github runners). Same fix as applied in release step for
top-level repos.
