meson: Add missing SDL dependency to system/main.c

When building QEMU configure with --disable-gtk --disable-cocoa
on macOS we get:

  ../system/main.c:30:10: fatal error: 'SDL.h' file not found
     30 | #include <SDL.h>
        |          ^~~~~~~
  1 error generated.

Fix by adding the SDL dependency to main.c it's CFLAGS contains
the SDL include directory.
