Fix duplicate stable acl config in python-glanceclient
Fix duplicate stable acl config in python-glanceclient

Change Ibff756e2f93179f2e6979ba9d784fbfcaff3651d added the stable acl
config, but then change I6fb79132d954c8cccdbd0c0584aa7acbe4655fef has
merged and we now have duplicate entries.  This is making the
project-config-gerrit change fail.

I think this got through because it's a check job and
I6fb79132d954c8cccdbd0c0584aa7acbe4655fef was around for a long
time before it got merged.
