tools headers uapi: Sync linux/in.h copy from the kernel sources

To get the changes in this cset:

  f275ee0fa3a0 ("IN_BADCLASS: fix macro to actually work")

The macros changed in this cset are not used in tools/, so this is just
to silence this perf tools build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/in.h' differs from latest version at 'include/uapi/linux/in.h'
