Subject: [PATCH] [Tests] Add retry on urchin setup which has no built in retry
 feature

Unlike other built in functions like git fetch or apt-get dependencies,
manual installations won't have retry by default, enabling retry could
help reduce the impact of network issues and furthur prevent getting
build error like Job #1956.21:
