ArmVirtPkg: adapt ArmVirtXen build to system memory end global variable
This fixes the ArmVirtXen build that was broken by r17835, which adds
a global variable mSystemMemoryEnd which is shared between a module
and a library it depends on.
Add the same global variable to the relocatable PrePi used by ArmVirtXen.
