[Buildroot] [RFC 2/2] packages: drop no longer needed busybox dependencies

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Now that the busybox package is careful to not build and install
applets that will conflict with the full-featured programs installed
by various packages, we can drop the optional dependency those
packages had on busybox.

Note: the list of packages is not complete, this is just a RFC version
to find out if that's the direction we want to take.
