Database encoding is set to SQL_ASCII

[treyhyde]

The dockerfile lists initdb params of UTF-8 but the databases that ship by default with this image are all SQL_ASCII.

I can reproduce this on master, but not on the 9.1 branch:

$ git checkout -b 9.1 origin/9.1
$ docker build -t postgresql .
$ docker run -d --name db postgresql
$ docker run --link db:db -i -t postgresql psql -h db -U docker -c '\l'

Looks like this regression was caused by #8 - could be an Ubuntu 14.04 thing. Investigating.
