mtier can be built only if one or more of other DAMON sample modules are
build-enabled.  This is because commit 66001f0476f4 ("samples/damon:
implement a DAMON module for memory tiering") on mm-unstable tree is not
connecting it on samples/Makefile.  Fix it by adding the connection on
samples/Makefile.
