KVM: selftests: Test guest_memfd binding overlap without GPA overlap

The guest_memfd binding overlap test recreates the deleted slot with GPA
ranges that overlap the still-live slot.  KVM rejects those attempts from
the generic memslot overlap check before reaching kvm_gmem_bind(), so the
test can pass even if guest_memfd binding overlap detection is broken.

Recreate the slot at its original, non-overlapping GPA and use guest_memfd
offsets that overlap the front and back halves of the other slot's binding.
Expand the guest_memfd so the back-half case remains within the file size.
