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

To pick the changes in: db243b7 ("net/ipv4/ipv6: Replace one-element arraya with flexible-array members") 2d3e5ca ("net/ipv4: Replace one-element array with flexible-array member") That don't result in any change in tooling, the structs changed remains with the same layout. 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.
