drm/tiny: pixpaper: Fix missing dependency on DRM_GEM_SHMEM_HELPER
The driver uses drm_gem_shmem_prime_import_no_map() and
drm_gem_shmem_dumb_create(), but the Kconfig currently selects
DRM_GEM_DMA_HELPER instead of DRM_GEM_SHMEM_HELPER. This causes
link failures when DRM_GEM_SHMEM_HELPER is not enabled.
Select DRM_GEM_SHMEM_HELPER to fix the build.
