[PATCH v3] of: unittest: for strings, account for trailing \0 in property length field

[Stefan M Schaeckeler <sschaeck@cisco.com>]

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.
