base-files: default_do_upgrade: accept & forward image extraction command

Browse Source 
get_image allows passing 2nd argument that is used in a pipe for
extracting firmware from a non-native format. By accepting such command
in default_do_upgrade we allow platforms to use this helper for vendor
specific images.
