The download_hc_build_pkgs.sh is used by
hc2vpp-csit-verify and hc2vpp-csit-verify-odl jobs.
These jobs download latest VPP packages
and unlike other HC CSIT jobs, build hc2vpp.
This patch removes vpp-dev/vpp-devel packages
from the list of installed VPP packages
to unify the environment with the other HC CSIT jobs.
