[PATCH v2] makedumpfile: -v shows if lzo or snappy support enabled or not

[WANG Chao]

It would be great to have makedumpfile -v to show if lzo or snappy
support is enabled or not, since --help prints too much and we have to
scroll back three screens to check it out.

For exmaple, If lzo and snappy support are enabled,

	$ ./makedumpfile -v
	makedumpfile: version 1.5.5 (released on 18 Dec 2013)
	lzo	enabled
	snappy	enabled

If both of them are disabled,

	$ ./makedumpfile -v
	makedumpfile: version 1.5.5 (released on 18 Dec 2013)
	lzo	disabled
	snappy	disabled
