os-release: Don't rebuild everytime

Update the os-release recipe such that it is not rebuilt unless
git reports something different.

To do this both the recipe and sstate caches must be disabled
but the impact with such a small recipe is low enough to be
acceptable.

Resolves: openbmc/openbmc#124
