Allow s390x non-root users to build fabric

The uid of the user invoking the make commands
is passed into docker containers during the build
process.  For s390x, if the uid does not exist
within the docker container's /etc/passwd file,
"git clone" commands fail.

This patch resolves this issue and would then
allow Jenkins Fabric verify jobs to successfully
run on z.
