QEMU uses a shorthand '-sdl' which maps to '-display sdl'. However, if
there are any options to be passed to SDL, the full command version must
be used. Everything seemingly worked for us until commit 5038b30043
introduced OpenGL support for SDL and added ',gl=on/off' option which as
mentioned above could have never worked with the shorthand version of
the command. Indeed starting a domain with an SDL display and OpenGL
enabled, QEMU produces a rather cryptic error:
-sdl: Could not open 'gl=on': No such file or directory
This patch provides fixes to both the SDL cmdline generation and the
test suite.

Support OpenGL when using SDL backend via -sdl,gl=on. Add associated
tests.
NB: Usage of DO_TEST_CAPS_LATEST in qemuxml2argv doesn't work in
this case because -sdl gl is not introspectable.
