[pkg-otr-team] Bug#817172: irssi-plugin-otr: plugin not in multiarch directory

[Florian Schlichting]

Sorry I probably should have pinged you; irssi-plugin-xmpp had
the same issue, see #817171, and I fixed it by making use of
DEB_HOST_MULTIARCH and specifying an explicit module path, see
https://anonscm.debian.org/cgit/collab-maint/irssi-plugin-xmpp.git/commit/?id=542ef1528821ffc0b048b38bb431918fcf02203f

Besides, irssi-plugin-otr needs to be rebuild anyways because we've had
an upload of a new major version of irssi, and since there has been some
ABI breakage in the past, the irssi folks introduced ABI versioning and
won't load anything that wasn't compiled against the same ABI version
(no change required, just a rebuild)
