conf: snd_config_save() - print arrays as [] not the internal representation

Browse source 
The internal represention of an array is:

{
	0 value1
	1 value2
	2 value2
	...
}

which is identicatal to shorter:

[
	value1
	value2
	value3
]

Always print the short format. It's more optimized and readable.
