ftrace,kcfi: Define ftrace_stub_graph conditionally
When CONFIG_FUNCTION_GRAPH_TRACER is disabled, __kcfi_typeid_ftrace_stub_graph
is missing, causing a link failure:
ld.lld: error: undefined symbol: __kcfi_typeid_ftrace_stub_graph
referenced by arch/x86/kernel/ftrace_64.o:(__cfi_ftrace_stub_graph) in archive vmlinux.a
Mark the reference to it as conditional on the same symbol, as
is done on arm64.
