i3lock-color should be removed before commiting this patch,
and we should add a note about this to the description. Like:
"You will need to install i3lock or one of its variants (like
i3lock-color) to make use of i3lock-fancy."

I'll contribute a Makefile upstream so that we can shorten the package definition.
