mk-sbuild installs pkgbinarymangler into the schroot.  Of of the
provided tools in pkgbinarymangler is pkgmaintainermangler.
pkgmaintainermangler is disabled by default, and enabled with
configuration.

A difference between launchpad builds of a synced package and an sbuild
is that the maintainer information will be different.

Enable pkgmaintainermangler to close this difference.
