perf diff: Change the default sort order to "dso,symbol"

Browse Source 
This is a more intuitive / more meaningful default:

$ perf diff | head -8
     9.02%     +1.00%  libc-2.10.1.so               [.] _IO_vfprintf_internal
     2.91%     -1.00%  [kernel]                     [k] __kmalloc
     2.85%     -1.00%  [kernel]                     [k] ext4_htree_store_dirent
     1.99%     -1.00%  [kernel]                     [k] _atomic_dec_and_lock
     2.44%             [kernel]
