ArmVirtPkg/ArmVirtQemuKernel: increase slack space for DTB
The relocatable build of ArmVirtQemuKernel is designed to be executed from RAM, and contains some scratch memory at the start of the image to use as a stack very early on, and to preserve the DTB image received from QEMU while it discovers and initializes memory. It turns out that 8 KB is a bit on the small side here, especially when executing with secure world emulation enabled, in which case there are additional nodes present. So increase the slack space to 32 KB. While at it, remove a stale Xen reference that was copy/pasted when this file was created.
