lib: Fix FUSE output on Raspbian
For some reason, 'ls' on raspbian invoked the fuse readdir() in a loop
where the first call had fuse_file_info * info set to NULL and
subsequent calls had info->nonseekable set to 1. Since we don't check
the value the info struct, this caused an infinite loop when trying to
list the contents of the fuse filesystem subdirectories of
/tmp/ouroboros/.
