The structures returned by this function contain pointers, which breaks on Wow64 if
the client is 32-bit (the service manager always runs in a 64-bit process).

This patch introduces a variant of ENUM_SERVICE_STATUS with offsets instead of pointers
and converts the structures on the client side.

The downside is that we need to buffer the data, but in return we can get rid of the
dummy buffer pointer.
