  Fix compile failure due to unused private field

In CMake release builds, RaidBackupFileSystem::mDiscSet was initialized but
never read, and this was detected by -Werror,-Wunused-private-field.

Now the field is totally compiled out of release builds, and by using the
correct preprocessor define, CMake and the Perl buildsystem now behave the
same.
