Subject: [PATCH 3/3] Fix compilation error when built with llvm17

With llvm17, building bcc hits the following compilation errors:
  ...
  /home/yhs/work/bcc/src/cc/bpf_module.cc:21:10: fatal error: llvm-c/Transforms/IPO.h: No such file or directory
   21 | #include <llvm-c/Transforms/IPO.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~
  /home/yhs/work/bcc/src/cc/bpf_module.cc:48:10: fatal error: llvm/Transforms/IPO/PassManagerBuilder.h: No such file or directory
   48 | #include <llvm/Transforms/IPO/PassManagerBuilder.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The above two files are removed by https://reviews.llvm.org/D144970 and https://reviews.llvm.org/D145835
