With "read-only-rootfs" in IMAGE_FEATURES, packages in ROOTFS_RO_UNNEEDED
are removed when building the rootfs. The list of packages to remove is
passed to the package manager and the list is sorted so that
update-alternatives provider is the last entry. This is with the
assumption that the last entry on the list/command line is removed last.
However, it turns out rpm does not care about "last on the command
line" and update-alternatives provider is removed before other the
packages get to run their %preun scripts for update-alternatives.
This leaves broken alternative symlinks in rootfs.
The fix is to first remove all but update-alternatives provider and
after that update-alternatives provider in its own remove() call.
