[PATCH 16/16] samples: watchdog: use 'userprogs' syntax

Kbuild now supports the 'userprogs' syntax to describe the build rules
of userspace programs for the target architecture (i.e. 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 necessarily provide libc.
