[Beignet] [Patch v2 06/10] runtime: fix clLinkProgram bug.

[xionghu.luo at intel.com]

From: Luo Xionghu <xionghu.luo at intel.com>

clLinkProgram need check the existence of "-cl-kernel-arg-info"
build_option of all the input_programs. User may link two SPIR
program and call clGetKernelArgInfo to query kernel args.
