user-selectable wic compression

Browse Source 
For boards which build and boot wic images, the user can optionally specify
a compression using the WIC_COMPRESSION_EXTENSION variable. By default "wic"
images are built, but if the user would prefer, say "wic.xz" images, simply
specify:

	WIC_COMPRESSION_EXTENSION = ".xz"

in the configuration (e.g. conf/local.conf).
