Remove Fedora repository fastmirror selection

Fast mirror selection somehow stopped working. If disabled, the
difference is around 20 seconds for the 'Prepare build environment' step
(2:49 versus 3:09), so while we are saving, currently it is not a lot.

Also remove explicit nodejs stream choice, it seems to be not needed
anymore (again).
