od: fix a bug that arises when skipping exact length of file

* NEWS: Document the bug fix.
* src/od.c (skip): Call fseek even when n_skip is exactly the
same as the length of the current file.  Otherwise, the next
iteration would use unadjusted input stream pointer, thus ignoring
the desired "skip".  Report and patch by Paul GHALEB.
