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

To pick up the changes in this cset:

  0312e94 ("treewide: fix typo 'unsigned __init128' -> 'unsigned __int128'")

This addresses these perf build warnings:

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

This required picking the const_true() define in linux/compiler.h as a
prep patch as that macro is used in the new linux/bits.h

Please see tools/include/uapi/README for further details.
