1. Common: Don't use MAP_FIXED on Linux …

   MAP_FIXED will clobber any existing memory mapping, and is not safe
   to use in a multi-threaded environment. Whether we like it or not,
   we are a multi-threaded environment, because Qt initializes before
   we get to main(), so it's already too late to safely use MAP_FIXED
   by the time we get there.
   
   Use MAP_FIXED_NOREPLACE instead. This is how MAP_FIXED should have
   behaved from the beginning.
   
   Obviously this means you'll need Linux 4.17+ and a semi-recent libc
   to use PCSX2 now. But if you're running a 6 year old unsupported
   kernel, you have bigger problems.
   
   Fixes "random" startup crashes.
