UBIFS: make debugfs files non-seekable

Turn the debufs files UBIFS maintains into non-seekable. Indeed, none
of them is supposed to be seek'ed.

Do this by making the '.lseek()' handler to be 'no_llseek()' and by
using 'nonseekable_open()' in the '.open()' operation.

This does mean an API break but this debugging API is only used by a couple
of test scripts which do not rely in the 'llseek()' operation.
