rawbaseparse: Drop incomplete frames at EOS

See https://bugzilla.gnome.org/show_bug.cgi?id=773666

This would ideally be solved in baseparse but that requires further
thought at this point, and in the meantime it would be good to have
rawbaseparse not assert on this but handle it gracefully instead.
