[PATCH i-g-t v3 3/3] lib/igt_kmod: Do not explicitly unload intel mei driver

[Daniele Ceraolo Spurio]

The mei driver is a child of i915 on discrete, but not on integrated.
This means we want to unplug it before removing i915 in the former case
but not in the latter. Therefore, instead of manually unloading the mei
driver, we can unbind i915 and leave it to the kernel to unplug all the
dependencies. This also means that we don't need to explicitly disable
the vtcon anymore.

The other 2 dependencies are left untouched:
- intel_ips uses symbol_get, so the automatic dependency detection won't
  unload it.
- the hotunplug test mentions that the sound driver can throw errors on
  i915 unbind, so we need to keep the explicit unload.
