[XAM] Return error in XamContentGetLicenseMask if we're not running from package

This fixes Halo CEA putting itself into a packaged/demo mode, where it doesn't perform some DVD checks & skips cache mounting, and probably other things too.
Now CEA should actually mount & write some stuff into the cache dir while the intro cinematic plays
(first writes a pak_stream.s3dpak file, then after a few seconds into the intro video it writes fileList.ps, which seems to have some strange values inside..)

I also added an exception to the code for arcade titles, since they'll probably need to use XamContentGetLicenseMask even when ran outside of a package.
