_add_dep: less aggressive backtracking (bug 693836)
In order to suppress the sort of aggressive backtracking that can
trigger undesirable downgrades as in bug 693836, do not backtrack
for an unsatisfied dependency if there's an available package in
the runtime package mask which was involved in a slot conflict and
satisfied all involved parent atoms. Instead, discard the current
depgraph in favor of other backtracking configurations that may
exist. This case would not have been encountered prior to the fix
for bug 692746 which enabled backtracking for the type of slot
conflict that is detected here.
