LISP: Fix a Clang warning

The warning was:
./print-lisp.c:401:11: warning: variable 'xtr_present' is used uninitialized
      whenever 'if' condition is false [-Wsometimes-uninitialized]
        else if (type == LISP_MAP_NOTIFY)
                 ^~~~~~~~~~~~~~~~~~~~~~~

./print-lisp.c:404:9: note: uninitialized use occurs here
        return xtr_present;
               ^~~~~~~~~~~

Moreover:
Remove unused 'interface.h' include.
