Fix build system regression and enhance string safety in core

- Restored missing if-block in CMakeLists.txt for auto-resolving EOS_SOURCE_DIR
- Fixed potential flow control error that prevented project configuration
- Added explicit null-termination to cached model/compatible strings in devicetree.c
- Replaced unsafe strcpy with strncpy in filesystem service initialization
- Verified changes with successful build and full ctest suite
