toaster: most-build-targets bug fixes

Fixes for the following for the "Most built targets" section of the
project page:
1) limit the number of most built targets to 5,
2) order the list of most built targets by build count,
3) select only those builds that had build status of 'fail', 'success',
or a BuildRequest of 'failed',
4) if there are no layers in the project then (on refresh) all of the
checkboxes in the 'Most built targets' list are disabled.

Note that per agreement with UI designer, the only sort on the most
target list is build count as described in (3) above; secondary sorting
is random.
