Fixup util.GetRootlessConfigHomeDir permission requirements

Do not require 0755 permissons for the ~/.config directory but require
at least 0700 which should be sufficient. The current implementation
internally creates this directory with 0755 if it does not exist, but if the
directory already exists with different perissions the current code returns
an empty string.
