Ignore bashate long-line warnings (E006)

Since Ic2532676e46e93f129d590d1fa7a044ef65f50fb bashate warns on
long-lines.  Traditionally, for whatever reason, devstack hasn't cared
too much about long lines unless it really damages readability.

So ignore this to avoid thousands of warnings on the long lines.  Note
even though released bashate doesn't have this, ignoring a missing
test doesn't matter.
