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.
