media: media-device: use strlcpy() instead of strncpy()
gcc-8 reports
drivers/media/media-device.c: In function 'media_device_get_topology':
./include/linux/string.h:245:9: warning: '__builtin_strncpy' specified
bound 64 equals destination size [-Wstringop-truncation]
We need to use strlcpy() to make sure the dest string is nul-terminated.
