tools headers UAPI: Sync linux/in.h copy with the kernel sources

To pick the changes in: 3218274 ("icmp: don't send out ICMP messages with a source address of 0.0.0.0") That don't result in any change in tooling, as INADDR_ are not used to generate id->string tables used by 'perf trace'. This addresses this build warning: Warning: Kernel ABI header at 'tools/include/uapi/linux/in.h' differs from latest version at 'include/uapi/linux/in.h' diff -u tools/include/uapi/linux/in.h include/uapi/linux/in.h Cc: David S.
