[git commit] ubiattach: add option -O

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=07fa09a9527b7c9f864799c4c1cab86b49f232ce
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

Some images do not have the default VID offset. The option -O must
be used to attach such images.
