* docker: do not require password for PostgreSQL superuser

A password is now required by the postgres Docker image which makes
initial setup (and our CI build) fail with the following error:

    postgres_1   | Error: Database is uninitialized and superuser password is not specified.
    postgres_1   |        You must specify POSTGRES_PASSWORD for the superuser. Use
    postgres_1   |        "-e POSTGRES_PASSWORD=password" to set it in "docker run".
    postgres_1   |
    postgres_1   |        You may also use POSTGRES_HOST_AUTH_METHOD=trust to allow all connections
    postgres_1   |        without a password. This is *not* recommended. See PostgreSQL
    postgres_1   |        documentation about "trust":
    postgres_1   |        https://www.postgresql.org/docs/current/auth-trust.html

See https://github.com/docker-library/postgres/issues/681.

* docker,kubernetes: create PostgreSQL "privacy" type before using it

Fixes the following error when setting up the database:

    postgres_1   | 2020-02-21 01:01:22.371 UTC [172] ERROR:  type "privacy" does not exist at character 200
    postgres_1   | 2020-02-21 01:01:22.371 UTC [172] STATEMENT:  CREATE TABLE public.playlists
    postgres_1   | 	(
    postgres_1   | 	    title text,
    postgres_1   | 	    id text primary key,
    postgres_1   | 	    author text,
    postgres_1   | 	    description text,
    postgres_1   | 	    video_count integer,
    postgres_1   | 	    created timestamptz,
    postgres_1   | 	    updated timestamptz,
    postgres_1   | 	    privacy privacy,
    postgres_1   | 	    index int8[]
    postgres_1   | 	);
    postgres_1   | ERROR:  type "privacy" does not exist
    postgres_1   | LINE 10:     privacy privacy,

* travis: do not run "docker-compose up" in detached mode

Rather, allow database to finish its setup procedure and grant
Invidious time to launch.
