[RFC,1/4] initramfs-framework: make RDEPENDS/RRECOMMENDS base package-specific

initramfs-framework itself is a meta package. It cannot be referenced in
PACKAGE_INSTALL directly, so the RDEPENDS/RRECOMMENDS do not have an
effect. So turn them into directives for initramfs-framework-base
instead.

Currently all users of initramfs-framework-* add
${VIRTUAL-RUNTIME_base-utils} explicitly to PACKAGE_INSTALL. For
`PACKAGE_CLASSES = "package_rpm"`, a dependency for `/bin/sh` is added by
RPM's shebang detection further hiding this issue.

Initially I stumbled upon this in a custom initramfs image with:

   PACAKGE_INSTALL = "initramfs-framework-base"

Having PACKAGE_CLASSES = "package_ipk", the initramfs did not contain a
shell. With PACKAGE_CLASSES = "package_rpm" however, busybox appeared
(unexpectedly) in the image.

Checking the rpm package's dependencies:

   $ rpm -qp build/tmp/deploy/rpm/noarch/initramfs-framework-base-1.0-r0.noarch.rpm --requires
   warning: Found bdb_ro Packages database while attempting sqlite backend: using bdb_ro backend.
   /bin/sh
   rpmlib(CompressedFileNames) <= 3.0.4-1
   rpmlib(FileDigests) <= 4.6.0-1
   rpmlib(PayloadFilesHavePrefix) <= 4.0-1
   rpmlib(PayloadIsZstd) <= 5.4.18-1

The shebang in the initramfs-framework-base scripts is added as a
dependency, pulling in busybox in my case.

Now I'm wondering if that's expected. I'm surprised that switching the
package manager results in additional dependencies getting pulled in.

This seems to have caused issues before, e.g.:
