meta-ros layer need to be present even if petalinux-image-minimal is built

[cg-sat]

The line inherit ros_distro_${ROS_DISTRO} in https://github.com/Xilinx/meta-petalinux/blob/master/recipes-core/packagegroups/packagegroup-petalinux-ros.bb#L6 makes it necessary that the meta-ros layer is lying around, because no other layer provides a ros_distro_*.bbclass.

To reduce the amount of code to checkout, I patched the meta-petalinux repository with the following patch:

diff --git a/recipes-core/packagegroups/packagegroup-petalinux-ros.bb b/recipes-core/packagegroups/packagegroup-petalinux-ros.bb
index c9d6de8..faffa50 100644

I'm using the rel-v2024.1 branch, but this issue is also present in the rel-v2024.2 branch.
