Bootstrap seeding only created missing files, so a WC24 file that had
been emptied (nwc24dl.bin, nwc24fl.bin, misc.bin) stayed at zero bytes
on every boot. WC24 rejects a zero-length download or friend list and
MKW reports that as a save error, which matters now that #7 lets KD
open while offline. A file is re-copied only when it is empty and the
payload's copy is not, so player data is never replaced.
Adapted from nx-mod/wiicompiled-nx d0149e66. That version falls through
to copy_file with copy_options::none, which fails on the existing empty
file; this one overwrites in that case only.
