rv: Make rtapp/pagefault monitor depends on CONFIG_MMU

commit 3d62f95bd8450cebb4a4741bf83949cd54edd4a3 upstream.

There is no page fault without MMU. Compiling the rtapp/pagefault monitor
without CONFIG_MMU fails as page fault tracepoints' definitions are not
available.

Make rtapp/pagefault monitor depends on CONFIG_MMU.
