buffet: extract common unittest helper functions into separate file
CreateValue, CreateDictionaryValue and ValueToString() functions
were duplicated in two unit test files in buffet. These functions
will be needed for even more unit tests in the future, so extract
them into their own unittest_utils.cc/.h so they can be reused
in other unit tests.
