stop changing the zend directory structure

Summary:
I tried to make life nicer for us by having just a flat level of directories, but it turns out lots of zend tests depend on their directory structure. I think we should give up and just exactly mirror them.

Facebook: Since phabricator can't handle that massive of a diff, this is
the script diff. I'll squash them when pushing.

Output of `git diff HEAD^ --name-status`: https://phabricator.fb.com/P2717586
