[PATCH 09/14] sstate: Avoid deploy_source_date_epoch sstate when unneeded

["Richard Purdie" <richard.purdie@linuxfoundation.org>]

This sstate task is only needed when depended upon, it can be skipped
if there are no tasks running that directly depend upon it.

This reduced the number of sstate tasks in something like an image
build.
