Fix shellcheck SC2230 > which is non-standard. Use builtin 'command -v' instead. Using `command -v` is POSIX compliant while `which` is not. Also to mention, `command -v` is a shell builtin whereas `which` is a separate busybox applet. Once applied to everything concerning OpenWrt we can disable the busybox feature `which` and save 3.8kB.
