Build: Only define HAVE_PROGRAM_INVOCATION_NAME if it is set to 1. 

HAVE_DECL_PROGRAM_INVOCATION_NAME is renamed to
HAVE_PROGRAM_INVOCATION_NAME. Previously,
HAVE_DECL_PROGRAM_INVOCATION_NAME was always set when
building with autotools. CMake would only set this when it was 1, and the
dos/config.h did not define it. The new macro definition is consistent
across build systems.
