build: capture build script auto-stash changes from 0.2.5 kernel/relibc/base build

The build-redbear.sh script auto-stashes working tree changes
in nested relibc and base source trees before running the
build. These changes were captured by the failed kernel
build attempt that hit the json-target-spec / kernel rust
toolchain mismatch (fixed in 0.2.5 by creating the local
0.2.5 branch).

Captured changes:
- local/recipes/kde/* : KDE Frameworks 6 source CMakeLists
  whitespace changes from the autostash (preserved)
- local/recipes/qt/qtbase/* : qtypes.h whitespace from the
  autostash (preserved)
- local/sources/kernel/Cargo.lock : dependency lock from
  the kernel relibc rebuild attempt
- local/sources/kernel/src/lib.rs : touched (mtime) by the
  build script's touch + make prefix command

This is a bookkeeping commit — the actual code changes
for the threading plan are on the 4 submodule branches
(kernel, relibc, base, libredox) and will be pushed
separately.

0.2.5 branch was created from 0.2.4 (HEAD cd3950072e) to
continue Phase 0 of the multi-threading plan work in a
clean branch.
