[PATCH v2 0/2] MR1263: kernelbase: Fix VerQueryValueW with no data

[Mark Jansen (＠learn-more)]

xul.dll from Mypal 27.9.4 has a resource entry without any data.
Windows returns this as null-terminated string, instead of pointing past the data.

The first commit adds a test,
the second commit fixes the bugs (and removes the todo_wine).

Original ticket for reference: https://jira.reactos.org/browse/CORE-15781
