ref(rootfs): remove timeout to pg_ctl start

[bacongobbler]

This timeout is tunable through the PGCTLTIMEOUT environment variable or, if not set, to 60 seconds. We can set this in the chart instead.

See https://www.postgresql.org/docs/9.4/static/app-pg-ctl.html

Thank you everyone for taking the time to review this. Since we're so far into the v2.8 release cycle I'm going to punt this change to v2.9.

For users who are hitting this, the following image and patch will work:

• postgres image: quay.io/deisci/postgres:git-a026223
• chart changes required: https://github.com/deis/charts/pull/378/files

If you're on versions prior to the deployment migration, you'll need to edit the deis-database-rc.yaml in your chart with the environment variable.
