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

To get the changes in this cset:

  65cab850f0ee ("net: Allow class-e address assignment via ifconfig ioctl")

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'
