Fix blhc by ensuring hardening flags are correctly applied. This patch modifies the Makefiles in `utils/uds/` and `utils/vdo/` to append CFLAGS and LDFLAGS, ensuring that hardening flags such as `-fPIE` and `-pie` are properly passed during the compilation and linking steps. Additionally, it ensures that `CPPFLAGS` are included where necessary, addressing the issues raised by the `blhc` check.
