Revert "add annex-distribute"

This reverts commit d387174aded760a984818d80f110eab3789b0700.

Because I can't make this work with the thingy that finds dead
symlinks, I tried this:

    function find_dead_symlinks {
        find $(find $dotfiles -mindepth 1 -maxdepth 1 -type d | grep -v /\.git | sed "s,^$dotfiles,$HOME,") \
            -type l \
            -exec sh -c '! test -r "$0" && ! git ls-files --error-unmatch "$0" >/dev/null 2>&1' {} \; \
            -print
    }

Which almost works because this works:

    find bin/ -type l -exec sh -c '! test -r "$0" && ! git ls-files --error-unmatch "$0" >/dev/null 2>&1' {} \; -print

But fails because git-ls-files gets the absolute paths. Just remove
this alias for now and don't keep broken symlinks here.
