KVM: arm64: nvhe: Fix missing FORCE for hyp-reloc.S build rule
[ Upstream commit a49b50a3c1c3226d26e1dd11e8b763f27e477623 ]
Add FORCE so that if_changed can detect the command line change.
We'll otherwise see a compilation warning since commit e1f86d7b4b2a
("kbuild: warn if FORCE is missing for if_changed(_dep,_rule) and
filechk").
