Make running the tests like in travis-ci easier (#92)

* Move testing logic from travis.yml to tests-ci.sh script

This way we can share this logic between travis CI and other systems
like for example a docker container.

* Move logic to create a testing environment to tests-environment.sh

As with the logic to execute the tests, this way we can share this logic
with other systems to tests linuxdeployqt.

* Install Qt also in tests-environment.sh

No reason to keep it separate from the rest as far as I know

* Wait until the X server is up and running

Otherwise we get into a racy situation.

* Add Dockerfile to create a testing container

This container tries to emulate the environment we have in travis-ci,
this way we can test whatever is failing on the CI locally.
