busybox: default ls color output, less search and truncate

Add features to busybox configuration:
- default color output for ls. ls still disables color for non-tty files
- support for less search (with slash /)
- support for less -S (truncate lines instead of wrapping)

Notably, this makes journalctl --no-pager | less -S much more usable. ls
colors were because I saw petitboot's busybox had them enabled.
