[Buildroot] [PATCHv2] system: sysvinit only selects busybox-show-others if busybox is enabled

BR2_PACKAGE_BUSYBOX_SHOW_OTHERS is a bit special. When Busybox is
enabled, it is a Busybox option. When Busybox is not enabled, it is a
stand-alone option, forcibly enabled.

So we can safely 'select' it without ensuring (via a 'depends on' or
another 'select') that Busybox is enabled.

However, the name of this option does not express the fact that it is
safe to select it without checking Busybox, which can lead to a bit of
time-consuming head-scratching.

To avoid future puzzlement from an unsuspecting observer, consider this
to be a Busybox option, and only select it when Busybox is enabled.

Hopefully, this will avoid people to go hunting like I did, and loose a
few precious minutes of hair-pulling... ;-]
