mkroot: add wget to pending build list, always rebuild .config when

$PENDING set, reset wordwrap after qemu exits (as well as in init script).

The wordwrap reset sequence was moved to the start of the init script
so command history editing wouldn't be borked in the emulated system,
but if the init script didn't run the host's command history editing
would stay borked. (QEMU's BIOS outputs something stupid that has to
be undone.)
