[PATCH] sstate: Add ability to hide summary output for sstate

[PATCH] sstate: Add ability to hide summary output for sstate

[Richard Purdie]

Its confusing to keep seeing sstate summary messages when hash equivalency is
active. This adds an option to control it. A default value is given which
maintains compatibility with different bitbake versions.
