LFS bug in tail

[Andreas Schwab]

This fixes an LFS bug in tail.  On systems where sizeof (size_t) < sizeof
(off_t) an overflow can occur when bytes_remaining is assigned, so that
tail on a big file > 4G does not work correctly.

        * src/tail.c (tail_bytes): Change type of bytes_remaining to off_t
        to avoid overflow.  Reported by Hans Lermen.
