Vagrant fixes (#3598)

* Qt5.5.1 link corrected.

* Qt5.5.1 tarball saves to project's root directory
since qt_deps_tarball used to have prefix of /vagrant.

* Add requests to update machine setup for both Travis and Vagrant

* Vagrant: use config variable in place of static string

* Vagrant: init and update submodules
