cico: don't cancel running build if REFSPEC (NM branch) differs
Allows passing via GitLab two rebuilds with the same OS but differing NM branches:
rebuild
@os:c9s
rebuild
@os:c9s
@build:nm-1-46
resulting in two c9s builds running at the same time, the first using NM
COPR repo for the main
branch and the second for the nm-1-46
.
@runtests:pass
