Move programs and support files out of usr for bootscripts

[DJ Lucas]

The following changes are required:

coreutils: mv /usr/bin/nice /bin findutils: mv /usr/bin/find /bin kbd: mv /usr/bin/{kbd_mode,openvt,setfont} /bin

Additionally, need to add '--datadir=/lib/kbd' to kbd configure line.

This was previously discussed on LFS-Dev here: ​http://archive.linuxfromscratch.org/mail-archives/lfs-dev/2006-June/057492.html and ​http://archive.linuxfromscratch.org/mail-archives/lfs-dev/2006-June/057552.html

I did not label this bug a blocker, but I do think that it is important and should be corrected before 6.2's release if editors willing.
