Busybox doesn't provide a similar tool so having it in
a separate package allows to us it in addition to busybox without having
to include all of util-linux.
Before it was part of the top level util-linux package.
Now it is a separate package util-linux-prlimit but the top level package
still RRECOMMENDS it so for most users nothing should change.
