m68k: defconfig: Update defconfigs for v6.6-rc1

  - Enable modular build of the new device model tests,
  - Enable modular build of the glob self-test on configs that didn't
    have it yet (visible since commit b67abaad ("kunit: Allow
    kunit test modules to use test filtering")),
  - Replace CONFIG_FB=y by CONFIG_FRAMEBUFFER_CONSOLE=y on the virt
    platform (the former is no longer needed since commit
    55bffc81 ("fbdev: Split frame buffer support in FB and
    FB_CORE symbols")), the latter is no longer auto-enabled since
    commit a5ae331e

 ("drm: Drop select FRAMEBUFFER_CONSOLE for
    DRM_FBDEV_EMULATION")).
