Revert "exec: limit system memory size" 



This reverts commit 818f86b8.

This was a work-around for bugs elsewhere in the system,
exposed by commit a53ae8e9:
    "hw/pci: partially handle pci master abort"
since that's reverted now, the work-around is not required for 1.7
anymore.
The proper fix is supporting full 64 bit addresses in the radix tree.
