dtc: Consider one-character strings as strings

Browse source 
When using overlays, a target-path property pointing to the root node is
quite common.  However, "dtc -O dts" prints it as a byte array:

    target-path = [2f 00];

instead of a string:

    target-path = "/";

For guess_value_type() to consider a value to be a string, it must
contain less nul bytes than non-nul bytes, thus ruling out strings
containing only a single character.  Allow printing such strings by
relaxing the condition slightly.
