Subject: [PATCH] Kirkwood: Fix tv sec/usec normalization in kwboot

`kwboot.c` had an issue where it failed to normalize the `tv` struct in
the case where the `tv_usec` field was 1000000, ie one second.

This caused issues on Fedora Linux 34, where `select` would return
`EINVAL`, preventing kwboot from communicating with the board.

BTW: I'm not 100% sure, but my understanding is that it is preferred (or
even required) to provide a "real name" in the tags. So it might be that
"Property404" is not enough here.

Thanks,
Stefan
