[PATCH] login: Use struct flock64 in utmp [BZ #24880]

[Florian Weimer]

Commit 06ab719d30b01da401150068054d3b8ea93dd12f ("Fix Linux fcntl OFD
locks for non-LFS architectures (BZ#20251)") introduced the use of
fcntl64 into the utmp implementation.  However, the lock file
structure was not updated to struct flock64 at that point.

	[BZ #24880]
	* login/utmp_file.c (file_locking_failed): Use struct flock64.
	(file_locking_unlock): Likewise.
