[TSan] Define C/C++ address ranges for SystemZ

The kernel supports a full 64-bit VMA, but we can use only 48 bits due
to the limitation imposed by SyncVar::GetId(). So define the address
ranges similar to the other architectures, except that the address
space "tail" needs to be made inaccessible in CheckAndProtect(). Since
it's for only one architecture, don't make an abstraction for this.
