lib/igt_kms: Make igt_display_require() + chamelium more robust

1. We don't reset Chamelium, as this generates extra unplug events if
   any of the ports is already connected which is often the case

2. We try to plug all the chamelium ports, it's a noop if they are
   already plugged

2. We wait for all the ports being connected:
   - if the port mapping is provided: wait for the ports to be connected
   - if there is no mapping: sleep(10) and hope for the best
