samples/damon/prcl: rename to have damon_sample_ prefix

DAMON sample module, prcl has its name 'prcl'.  It could conflict with
future modules, and not very easy to identify it by name.  Use a prefix,
"damon_sample_" for the name.

Note that this could break users if they depend on the old name.  But it
is just a sample, so no such usage is expected, or known.  Even if such
usage exists, updating it for the new name should be straightforward.
