[Libguestfs] [libnbd PATCH v2 1/3] copy: rename DESTINATION_IS_ZERO_OPTION to TARGET_IS_ZERO_OPTION

Both "--destination-is-zero" and "--target-is-zero" are parsed as DESTINATION_IS_ZERO_OPTION internally. By renaming the enum constant to TARGET_IS_ZERO_OPTION, we reduce the max width of the "copy/main.c" file to 79 characters. Rename the variable "destination_is_zero" to "target_is_zero" as well, for consistency.
