Disable memory debugging features in non-developer build

Browse Source 
The two memory debugging features: ISC_MEM_DEFAULTFILL
(ISC_MEMFLAG_FILL) and ISC_MEM_TRACKLINES were always enabled in all
builds and the former was only disabled in `named`.

This commits disables those two features in non-developer build to make
the memory allocator significantly faster.
