samples/damon/wsse: rename to have damon_sample_ prefix

Patch series "mm/damon: misc cleanups".

Yet another round of miscellaneous DAMON cleanups.

This patch (of 6):

DAMON sample module, wsse has its name 'wsse'.  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.
