Can't build ovsdpdk image on CentOS

[fanguiju]

Failed to build ovsdpdk image when I execute the `./build.py ovsdpdk` on CentOS7, the log output was as follows:

INFO:kolla.common.utils:=========================
INFO:kolla.common.utils:Successfully built images
INFO:kolla.common.utils:=========================
INFO:kolla.common.utils:base
INFO:kolla.common.utils:===========================
INFO:kolla.common.utils:Images that failed to build
INFO:kolla.common.utils:===========================
ERROR:kolla.common.utils:ovsdpdk-db Failed with status: matched
ERROR:kolla.common.utils:ovsdpdk-vswitchd Failed with status: matched

Then we found out that using the `centos+source` does not build the ovsdpdk image and it will be skipped.
https://github.com/openstack/kolla/blob/9ef9cbeb8f3504a4d80716e5e6ae7e9e6bb372d6/kolla/image/build.py#L101

So, I thought it should print the unambiguous and more friendly logs, and them users can find problems easy.

Master (train too) says precisely that ovsdpdk images are not buildable for centos:

Change abandoned by "Marcin Juszkiewicz <email address hidden>" on branch: master
Review: https://review.opendev.org/c/openstack/kolla/+/577644
Reason: We have 'unbuildable images' dict now which does similar thing.
