Tests: Activate tests accidentally excluded from Xcode

The generator name is "Xcode", not "XCode".  Fix this typo.  Explicitly
exclude the SubDirSpaces test on Xcode because it does not work.  Also
tell the RunCMake.File_Generate test when Xcode is not multi-config so
it can exlcude the OutputConflict case.
