Removed LOCATIME and TZDIR stuff since it is now handled correctly by
share/zoneinfo and was just duplicated here.

Fixed the directory owner ships on the inst1 floppy by adding all of the
directories that get created on the floppy to INST1_DIR, since cpio was
not picking up the source dir protections, but instead using the current
process uid, gid, and umask values.

Removed /bin/df from inst1 to make room for mount_pcfs.  Also removed
/etc/disktab since it just got overwritten by the install tools.

Removed zcat from INST2_CPIO since it is now installed from the
INST2_FILES files on the floppy.  This fixes things so that all
of the gzip tools get linked to the same image.

Much of the .if machine i386 stuff moved to be system independent
since it really was.

Added sd1 support to the inst1 and kc floppies.  No room for wd1 support,
oh well.

Fix permissions on top level of floppy, it was not getting set.
