Fix SIGITIN hang with apt-get
Fix an issue where apt-get consistently hangs due to a SIGTTIN being
received. This occurs on a 'vanilla' devstack-gate VM, when running an
ironic-grenade job.
Upstream has a bug related to this:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=555632
http://www.gnu.org/software/libc/manual/html_node/Job-Control-Signals.html
Macro: int SIGTTIN
A process cannot read from the user's terminal while it is running
as a background job. When any process in a background job tries to
read from the terminal, all of the processes in the job are sent a
SIGTTIN signal. The default action for this signal is to stop the
process. For more information about how this interacts with the
terminal driver, see Access to the Terminal.
