Daniel Borkmann 9d876e79df bpf: fix unlocking of jited image when module ronx not set ... Eric and Willem reported that they recently saw random crashes when JIT was in use and bisected this to 74451e66d5 ("bpf: make jited programs visible in traces"). Issue was that the consolidation part added bpf_jit_binary_unlock_ro() that would unlock previously made read-only memory back to read-write. However, DEBUG_SET_MODULE_RONX cannot be used for this to test for presence of set_memory_*() functions. We need to use ARCH_HAS_SET_MEMORY instead to fix this; also add the corresponding bpf_jit_binary_lock_ro() to filter.h.
