Create 'infra' type of images

If image is always built same way then it is considered 'infra'.
BINARY_SOURCE_IMAGES variable lists toplevel binary/source images.

There is a switch "--infra-rename" to enable renaming of infrastructure
images. Disabled by default to keep compatibility (will be enabled in
future patch).

Implements: blueprint infra-images
