dtc: Consider one-character strings as strings
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.
