fix(susfs-patches): narrow fold_filemap stub to only 2024-07

The __fold_filemap_fixup_entry function was backported to the Android
common kernel starting in the 2024-08 os_patch_level. Only the 2024-07
kernel lacks it. Condition the stub on both sublevel <=30 AND
os_patch_level == 2024-07 so 2024-08+ kernels use the real declaration.
