Adhemerval Zanella e442e40de5 io: Consolidate lockf implementation 
With internal fcntl64 internal (commit 06ab719d), it is possible to
consolidate lockf implementation by using the LFS fcntl interface
instead of using arch and system-specific implementations.

For Linux, the i386 implementation is used as generic implementation
by replacing the direct syscall with fcntl64 call.  The LFS symbol
alias for default LFS ABI (__OFF_T_MATCHES_OFF64_T) is used to avoid
the duplicate symbol (instead of overriding the implementation with an
empty file).

For Hurd lockf64 semantic is changed: previous generic lockf64
implementation returned EOVERFLOW if LEN input is larger than 32-bit
off_t.  However, Hurd fcntl64 implementation for F_GETLK64, F_SETLK64,
and F_SETLKW64 do accept off64_t inputs (__f_setlk accepts only off64_t
inputs).

Checked on i686-linux-gnu and x86_64-linux-gnu along with a i686-gnu
build.

	* io/Makefile (tests): Add tst-lockf.
	* io/lockf.c (lockf): Use __fcntl and only define for
	!__OFF_T_MATCHES_OFF64_T.
	* io/lockf64.c (__lockf64): Call __fcntl64 and alias to lockf for
	__OFF_T_MATCHES_OFF64_T case.
	* io/tst-lockf.c: New file.
	* sysdeps/unix/sysv/linux/i386/lockf64.c: Remove file.
	* sysdeps/unix/sysv/linux/arm/lockf64.c: Likewise.
