initscripts: new package
The folder init.d is currently installed by default since it's part of
our skeleton.
This patch creates a package out of it and make busybox/sysvinit depends
on it.
This way, if you chose another init, you don't end up with a useless
init.d folder.
[Thomas:
- make the initscripts package selectable via a hidden bool
- remove some unneeded changes in sysvinit.mk.]
