[PATCH] fcntl: define F_GETLK, F_SETLK, F_SETLKW to 64-bit versions if __OFF_T_MATCHES_OFF64_T is enabled

If __OFF_T_MATCHES_OFF64_T is enabled, the behavior of sys_fcntl should
be the same as if __USE_FILE_OFFSET64 is enabled. This patch adds
required definitions.

Tested with aarch64/lp64 and aarch64/ilp32

	* sysdeps/unix/sysv/linux/bits/fcntl-linux.h: define F_GETLK,
	  F_SETLK, F_SETLKW to 64-bit versions depending on
	  __OFF_T_MATCHES_OFF64_T
