Rename 'overlayfs' module as per upstream name 'overlay'

[gdm85]

Module has been renamed upstream: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ef94b1864d1ed5be54376404bb23d22ed0481feb

The reason is that some distros might want to keep 2 modules, 'overlay' and 'overlayfs'.

However this is not the case for the kernel shipped by Ubuntu; would it be possible to support the new module name?

@brad-figg no logs are needed to diagnose this problem. Module name has been like this since kernel 3.0+

I am investigating if this change is possible/desired in Ubuntu 14 LTS.

I found out that the overlayfs version in Ubuntu doesn't support workdir option, thus it's not the same thing as upstream 'overlay'.

Closing.
