qemu: support graphic hw acceleration

:Release Notes:
support "runqemu qemux86" to use hw acceleration options

:Detailed Notes:
Currently qemux86 generated from oe build fails launching with hw
acceleration options (e.g. -vga virtio -display sdl,gl=on)
on X11 WM linux host.
- To support acceleration options, the following should be required.
qemu should be compiled with "--enable-opengl".
- libepoxy should be compiled with "-enable-x11" as well as
"-enable-egl" (These options are not mutual exclusive.).

:Testing Performed:
Tested locally on Ubuntu 18.04.
$ runqemu qemux86 kvm slirp

:QA Notes:
None

:Issues Addressed:
None
