scripts/combo-layer: ignore merge commits

The combo-layer tool had trouble handling merge commits as they were
included in the revision list but not the patches; these are now
excluded from the revision list. Note however that this will not handle
merge commits that resolved a conflict; since "git format-patch" cannot
construct a linear change history over such merges there is nothing we
can currently do with these.
