cleanup: fix some list comprehension redefinitions of existing vars

In all the remaining cases the comprehension variable is used for the same
thing as a previous loop variable.

This will mute some pyflakes "list comprehension redefines" warnings.

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"
}
