bitbake: generate new overrides syntax for RDEPENDS
bitbake: generate new overrides syntax for RDEPENDS

* generate new syntax for OE recipes to match:
  https://lists.openembedded.org/g/openembedded-architecture/message/1260
  https://lists.openembedded.org/g/openembedded-architecture/message/1279
  https://lists.openembedded.org/g/openembedded-architecture/message/1291

* this was already done with conversion script in meta-ros with:
  https://github.com/ros/meta-ros/pull/902
  but for new ROS Distribution releases we want to generate new
  syntax directly with superflore.

* it's not conditional based on OE release series, because all
  currently supported versions (dunfell, hardknott, honister)
  do support new syntax (when latest bitbake revision from
  corresponding branch is being used).

* fixes https://github.com/ros-infrastructure/superflore/issues/284
