of: unittest: for strings, account for trailing \0 in property length field

Browse Source 
For strings, account for trailing \0 in property length field:

This is consistent with how dtc builds string properties.

Function __of_prop_dup() would misbehave on such properties as it duplicates
properties based on the property length field creating new string values
without trailing \0s.
