Add sys_fcntl argument interfaces to linux_record_tdep. 

* linux-record.h (linux_record_tdep): Add fcntl_F_GETLK,
	fcntl_F_GETLK64, fcntl_F_SETLK64 and fcntl_F_SETLKW64 to be
	interfaces.
	* i386-linux-tdep.c (I386_LINUX_RECORD_FCNTL_F_GETLK,
	I386_LINUX_RECORD_FCNTL_F_GETLK64,
	I386_LINUX_RECORD_FCNTL_F_SETLK64,
	I386_LINUX_RECORD_FCNTL_F_SETLKW64): New macros. The values
	of I386 Linux sys_fcntl arguments.
	(i386_linux_init_abi): Set macros values to linux_record_tdep.
	* linux-record.c (record_linux_system_call): Change to use
	the interface in linux_record_tdep in sys_fcntl and
	sys_fcntl64.

	* linux-record.c (record_linux_system_call): Fix the process
	record build error about type in CYGWIN.
