updated isiboot

[Izumi Tsutsui <tsutsui%ceres.dti.ne.jp@localhost>]

I'm not sure if there are any (possible) users of this port other than me,
but I've put updated isiboot program that works on NetBSD/i386 -current:
ftp://ftp.NetBSD.org/pub/NetBSD/arch/luna68k/isiboot-20110717.tar.gz
(old one did work on 1.5.3, but not on at least 5.1 and 5.99.54)

See luna68k installation instructions about isiboot details:
http://www.NetBSD.org/ports/luna68k/install.html
(well, this document should also be updated to mention sysinst etc..)

Eventually, this isiboot.c utility should be written
as a daemon like rbootd(8) or ndbootd(8)...
