CONFIG_UPROBES is enabled by CONFIG_UPROBE_EVENTS, which gets enabled by CONFIG_FTRACE. Therefore add this config to selftests/mm/config so that CI systems can include this config in the kernel build.

If we need UPROBES we should enable UPROBES explicitly, otherwise it looks like we're just randomly enabling FTRACE even though it's not used itself. If it's a dependency for UPROBES and we also enable UPROBES that's a bit more obvious.
