The OVN_BUILD_FROM_SOURCE was introduced by a patch in DevStack [0]
which allows for stacking OVN using packages instead of compiling it
from source (by default that flag is False). Now the jobs compiling OVN
(master ones) should include this flag.
Also since the logs are on different paths depending on how OVN is
installed, we are telling zuul to collect it properly for the compiled
version (this inconsistency is something that perhaps we should fix in
DevStack itself).
