samples: auxdisplay: use 'userprogs' syntax
Kbuild now supports the 'userprogs' syntax to compile userspace programs for the same architecture as the kernel. Add the entry to samples/Makefile to put this into the build bot coverage. I also added the CONFIG option guarded by 'depends on CC_CAN_LINK' because $(CC) may not provide libc.
