[PATCH 12/17] bootwrapper: Make set_cmdline() create /chosen if it doesn't exist.

[Segher Boessenkool]

No way.  The /chosen node should _always_ exist; you might
argue for the bootwrapper creating it if it isn't there,
but don't only do it when setting "bootargs", just always
do it (and do it early).
