Simplify run cmd for archs other than amd64

Requirement

Currently have a strictly explicit approach to target architecture selection i.e. you will need to specify the platform target

This breaks the fundamental assumption that

make images

kamel install
kamel run Basic.java

just works regardless of target architecture.

Let me see if I can get this fixed, by better understanding how integration images for various platforms can be built e.g. -Djib.from.platforms=. In regression testing there was an issue with upgrading when -Djib.from.platforms=linux/amd64,linux/arm64 was always set, which lead to the -t builder.platforms trait.
