libtracefs: Use tracefs_cpu_*_buf() calls for iterator
The iterators were created before the tracefs_cpu_buffered_read_buf() and
tracefs_cpu_flush_buf() which returns a kbuffer to iterate. Instead of
having to manage its own kbuffer, use the one that is managed by the
tracefs_cpu.
This will also allow the iterator to use the memory mapping code.
