tools headers: Synchronize linux/build_bug.h with the kernel sources

To pick up the changes in:

  6ffd853b0b10e1e2 ("build_bug.h: correct function parameters names in kernel-doc")

That just add some comments, addressing this perf tools build warning:

  Warning: Kernel ABI header differences:
    diff -u tools/include/linux/build_bug.h include/linux/build_bug.h

Please take a look at tools/include/uapi/README for further info on this
synchronization process.
