configure: Fix SDL2 typo by referencing value

Browse Source 
During configuration of SDL2, variable enable_grub_emu_sdl2 is checked
whether to throw an error message. However, error could not happen
because two unequal strings were compared. Fix this by referencing
value of enable_grub_emu_sdl2, not name.

Fixes: 17d6ac1a7 (emu: Add SDL2 support)
