OpenCL: Avoid potential buffer overflow in cmdutils_opencl.c

Browse Source 
The opt_opencl_bench function copied the device name using strcpy without checking if the source string was larger.
This patch fixes this by replacing the strcpy with av_strlcpy, with the string copy size capped to the destination buffer size.
