Fix WOLFSSL_NO_MALLOC build.

[philljj]

Description

This issue is in the wolfCrypt test application only, not the library proper.

Fix memset overrun build error:

error: 'memset' will always overflow; destination buffer has size 1024, but size argument is 1040 [-Werror,-Wfortify-source]

The static array NO_MALLOC version of large_output is shorter than the dynamic malloc version.

Testing

cd src || exit 1            
                                                             
./configure \                                                
  --enable-staticmemory \
  CPPFLAGS=-DWOLFSSL_NO_MALLOC \                             
 || exit 1                                                   
                                                             
make || exit 1                                               
                                                             
./wolfcrypt/test/testwolfcrypt || exit 1                     
                                                             
echo "built wolfssl"
