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.
