Stop compiling vmenter.S with OBJECT_FILES_NON_STANDARD to skip objtool's
stack validation now that __svm_vcpu_run() and __svm_sev_es_vcpu_run()
create stack frames (thoughthe former's effectiveness is dubious).
Note, due to a quirk in how OBJECT_FILES_NON_STANDARD is handled by the
build system, this also affects vmx/vmenter.S. But __vmx_vcpu_run()
already plays nice with frame pointers, i.e. it was collateral damage when
commit 7f4b5cde2409 ("kvm: Disable objtool frame pointer checking for
vmenter.S") added the OBJECT_FILES_NON_STANDARD hack-a-fix.
