Colin Walters 12dc565b00 core: Set installonly to ensure we only have one kernel
The goal here is to support `override replace kernel.x86_64.rpm`.

There's a whole lot of logic in libdnf to support having multiple
kernel packages installed.  AIUI, that was implemented because:

1) The kernel is the biggest source of regressions
2) It'd be quite noticeable if all of your kernel modules were deleted

Of course point 2) applies to a lot of userspace too...that's something
rpm-ostree fixes of course.

Anyways, in some testing all we need to do really is just turn that
logic off unconditionally.

Closes: https://github.com/projectatomic/rpm-ostree/issues/946

Closes: #1228
