app-emulation/qemu-9999: Drop sdl-1.2 support

QEMU has deprecated sdl-1.2 support nearly a year ago (in
upstream commit of e52c6ba3414). It's not removed yet, but it
soon will be. Therefore, drop support for it in our ebuild. This
is achieved by basically dropping old 'sdl' use flag and then
renaming 'sdl2' to 'sdl'.
