sortdict: add iteritems method

Future patches will start using sortdict for log operations where order is
important. Adding iteritems removes the headache of having to remember to use
items() if the object is a sortdict.

fixbundle() {
    grep -v 'saving bundle' | grep -v 'saved backup' | \
        grep -v added | grep -v adding | \
        grep -v "unable to find 'e' for patching" | \
        grep -v "e: No such file or directory"
