V2 changes: addressed feedback from the first review round

Why this? Why now?

1. I think we are heading towards a reality where some kind of working
GL is a 'must' for any kind of UI work.
2. Typically people build images and then transfer them to the NUC or
even target boards for testing - using qemu would be less awkward.
3. Current qemu configuration is basically useless here, as it only
provides a very slow software GL driver from mesa.

0. TLDR:

$ . oe-init-build-env build-virgl
$ bitbake core-image-sato-sdk
$ runqemu kvm gl
$$ run glxgears or any other GL-capable binary inside qemu

1. qemu is switched over to use gtk frontend. I simply couldn't get SDL 
frontend to work properly, it only displays a blank black window or doesn't 
start at all. Same thing happens with qemu binaries provided by Fedora and 
opensuse (Ubuntu's qemu lacks virgl support). Seems like SDL support has 
regressed.

2. While the components are built against the most minimum necessary 
mesa-native set (gbm, egl, dri with no drivers), libepoxy loads and uses the 
host GL implementation (through a chrpath hack). This is both to save build 
times, and because the host is likely to have a set of drivers more 
appropriate for the physical machine (e.g. proprietary nvidia stack, 
although I didn't test that).

3. I tested this with
- glamor X server
- weston compositor with drm backend (build core-image-weston, then edit 
  weston.ini in the image to use drm backed instead of fbdev).
- kmscube
- glxgears
- https://www.geeks3d.com/gputest/

The latter two show FPS that is similar to running them directly on the host.

4. Some things I am not sure about:

 - how much of a 'default' should this be for running qemu. It works for me, 
but other people might find it less stable compared to the existing 
sdl-vmware-swrast setup.

- what other tests and demos could be run

- how could this be tested on the autobuilder. I wrote an oe-selftest for 
this, but it does require an X session, and ability to create opengl 
contexts on the host.

The following changes since commit 1ee53881eea3a7ca4d4f6a5ca9c4c6e6488d2348:

  perl: fix yet another race failure (2019-01-14 17:38:24 +0000)
