toaster: fix tasks showing as NoExec

Tasks without script type information showed by default
as NoExec; this happens for all Prebuild or Covered
tasks, as script type information comes only on TaskStarted
event. Such a default value may drive confusion, as NoExec value
should be reserved for the NoExec-flagged tasks.

This patch adds a new default value named Unknown that will be
used for all tasks that don't have script type information
available.

toaster: fix path to buildstats file

The buildstats file path changes based on the
optional PE variable that may be defined for a
recipe.

The toasterui simply ignored the PE value, and
as such it didn't correctly reach buildstats files
for some of the tasks.

This patch fixes the issue.

hob: refresh tables when the user is redirected to Edit packages

When the build fails and I click "Edit packages", we should be returned
to the tab we launched the build from. Hob should remember the tab,
not the search state.

toaster: task with outcome 2 (sstate), should have sstate_result!=0

0 (not applicable) is not a valid sstate_result for tasks with
outcome 2 (sstate), which should return 3 (restored), 2
(failed) or 1 (missed).
Sstate_result for tasks with outcome 2 is equal to the outcome
of _setscene corespondent task.
