Adjust the callers to remove the redundant sizeof() arguments ahead of treewide changes, since it needs a manual adjustment for the newly named sized_strscpy() export.

A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on its destination buffer argument which is _not_ the case for `strncpy`! In this case, we are able to drop the now superfluous `... - 1` instances because `strscpy` will automatically truncate the last byte by setting it to a NUL byte if the source size exceeds the destination size or if the source string is not NUL-terminated. I've also opted to remove the seemingly useless char* casts. I'm not sure why they're present at all since (after expanding the `ifr_name` macro) `ifr.ifr_ifrn.ifrn_name` is a char* already. All in all, `strscpy` is a more robust and less ambiguous interface while also letting us remove some `... -1`'s which cleans things up a bit.

Instead of teaching the driver to open a FD in multiple ways, it can rely on management layer to do it on its behalf. For example, this allows inheriting a preconfigured device fd or a simple socketpair() setup, without further arguments, privileges or system access by UML.
