[BusyBox] tab search bug in ash

[Andrew Hall]

I haven't started looking through the code, but from experimentation it
seems that the tab-edt like function is hard-coded to only look in
/bin:/sbin. I noticed this because it finds commands in these directories
even when I set the PATH statement to empty.
