package/duma: fix build with gcc 11
Fix the following build failure with gcc 11:
In file included from dumapp.cpp:39:
dumapp.h:88:49: error: ISO C++17 does not allow dynamic exception specifications
88 | void * DUMA_CDECL operator new(DUMA_SIZE_T) throw(std::bad_alloc);
| ^~~~~
While at it, also drop DUMA_CPP which does not seem to be set since the
addition of the package back in 2013 in commit
