[git commit] find_applet_by_name: loop index should be signed

[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=b22061718db0111f9e7474f9b60aef02456ac070
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

was intended to terminate when j goes negative, so j needs to be signed.
