(fhandler_base::lseek): Include high order bits in return.

[Christopher Faylor]

The patch below causes compile warnings to be issued for cygwin when
stat.h is included:

In file included from /netrel/generic/cygwin/newlib/libc/include/sys/fcntl.h:164,
                 from /netrel/generic/cygwin/winsup/cygwin/include/fcntl.h:14,
                 from /netrel/generic/cygwin/winsup/testsuite/winsup.api/crlf.c:144:
/netrel/generic/cygwin/newlib/libc/include/sys/stat.h:144: warning: `struct stat64' declared inside parameter list
/netrel/generic/cygwin/newlib/libc/include/sys/stat.h:144: warning: its scope is only this definition or declaration, which is probably not what you want

It could presumably cause errors for unistd.h/_lseek64 as well.

I noticed this problem while trying to run the cygwin test suite.
