packae/duma: do not build test programs

Building test programs fails for a static link, because duma.a redefines
memcpy and strcpy, which are already present in the C library.

Fixes quite some build failures:

    ...

Also rename patches according to the new naming scheme.

+Do not build test programs
+
+Biulding test programs does not work when we want to do a static link,
+because duma.a redefines memcpy and strcpy, so the link fails.
