[rancid] netscreen login script (nlogin)

[heasley]

A user is having trouble collecting a netscreen box from a centos7 host.
We've discovered that the following change fixes the problem, but the
cause is unclear.  So, I'm reluctant to commit this with knowing that it
does not break collection for some sample of users.

Could other netscreen owners try this patchi, please?
