rpm: add a 4.x recipe

The dnf stack is written and tested against rpm 4.x. So if we want to use dnf for packaging,
we should also use rpm 4 - there's simply too much work involved in making rpm 5 work with it due
to significant API differences, and supporting that going forward.

+Subject: [PATCH] When cross-installing, execute package scriptlets without
+ chrooting into destination rootfs
+
+This is triggered only when RPM_NO_CHROOT_FOR_SCRIPTS environment variable is defined.
+Otherwise they will trigger an explosion of failures, obviously.
