duma: not available on non-MMU platforms 

By design, building duma on Blackfin and other non-MMU platforms is
quite useless: it uses page mappings to detect buffer overrun and
use-after-free programming errors. Therefore, this commit simply marks
duma as not available on non-MMU platforms.

Fixes:
