fix(Makefile): resolve multiple definitions and missing YukawaScreening link

- Remove 4 duplicate objects (dftu_nao_fs_k/for_r/fs_r/str_r.o) from
  OBJS_HAMILT_LCAO; they are already listed in OBJS_DFTU and both
  lists merge into OBJS_ABACUS, causing "multiple definition" linker errors.
- Add missing yukawa_screening.o to OBJS_SRCPW so YukawaScreening::*
  symbols resolve; it is already present in CMakeLists.txt module_pwdft.

Verified with `make -n` (dry-run): dftu_nao_fs_k.o appears exactly once
in the final link line; yukawa_screening.o is compiled from
source_pw/module_pwdft/yukawa_screening.cpp.
