Use repo clone as opposed to raw copy in travis
Use repo clone as opposed to raw copy in travis

Travis currently copies our repository so that it is named properly.  However, this
discards the .git metadata.  Elements of our build use tools like "git ls-files"
and the lack of git metadata breaks them.  There's really no reason we need to
copy the files, so lets just clone/link them instead and thus retain the .git metadata
and be more efficient at the same time.
