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