btrfs: send: add OTIME as utimes attribute for proto 2+ by default 



When send v1 was introduced the otime (inode creation time) was not
available, however the attribute in btrfs send protocol exists. Though
it would be possible to add it for v1 too as the attribute would be
ignored by v1 receive, let's not change the layout of v1 and only add
that to v2+.  The otime cannot be changed and is only informative.
