Naivediff fails when layers are created directly on top of
each other. Other graphdrivers which use naivediff already
skip these tests. Until naivediff is fixed, skip with overlay2
when running tests on a kernel which causes naivediff fallback.
Fix applydiff to never use the naivediff size when not applying
changes with naivediff.

Adds a new overlay driver which uses multiple lower directories to create the union fs.
Additionally it uses symlinks and relative mount paths to allow a depth of 128 and stay within the mount page size limit.
Diffs and done directly over a single directory allowing diffs to be done efficiently and without the need fo the naive diff driver.
