pbrd: Fix nearly impossible truncation
Since we are writing into the name field which is PBR_MAP_NAMELEN
size, we are expecting this to field to be at max 100 bytes.
Newer compilers understand that the %s portion may be up to
100 bytes( because of the size of the string. The %u portion
is expected to be 10 bytes. So in `theory` there are situations
where we might truncate. The reality this is never going to
happen( who is going to create a nexthop group name that is
over say 30 characters? ). As such we are expecting the
calling function to subtract 10 from the size_t l before
we pass it in to get around this new gcc fun.
Fixes: #2163
