bcache.h: Bring version information to the latest kernel version.
bcache-super-show.c: Add setsize for caching devices. This indicates
the number of devices in caching set.
Testing done:
1.0 make-bcache with --label option and checking back to see if
bcache-super-show shows the devices.
2.0 bcache-super-show does not bail if version is 5.
3.0 bcache-super-show shows the correct setsize.
