sys-apps/iproute2: fix UB in strncpy (e.g. truncated ip route output)
Fix overlapping buffers passed to strncpy which is UB. format_host_rta_r writes
to the buffer passed to it, so hostname (derived from b1) & b1 partly overlap.
This gets worse with sys-libs/glibc-2.37 where the ip route output can be truncated,
but it was UB anyway and you can see it occurring w/ glibc-2.36.
