Prefer `strscpy_pad` as it's a more robust interface whilst maintaing
zero-padding behavior.
There may have existed a bug here due to both `tbl->repl.name` and
`info->name` having a size of 32 as defined below:
| #define XT_TABLE_MAXNAMELEN 32
This may lead to buffer overreads in some situations -- `strscpy` solves
this by guaranteeing NUL-termination of the dest buffer.
