Bug#680391: lintian: precise now released, remove data.tar.xz-member-without-dpkg-pre-depends

[shawn <shawn@jengr.tk>]

Source: lintian
Version: unstable
Severity: minor

The data.tar.xz-member-without-dpkg-pre-depends

pedantic warning can now be dropped, as precise has been released (lucid-->precise)
and the two old update-from targets (squeeze and precise) both have xz support.
