rm_conffile() /etc/modprobe.d/ipw3945 on upgrades

[Loïc Minier]

        Hi

 Back in gutsy, linux-restricted-modules-common used to ship a
 /etc/modprobe.d/ipw3945 conffile.  In hardy, this conffile wasn't
 shipped anymore, but wasn't removed on upgrades.  (The modprobe.d file
 served starting a binary only daemon but ipw3945 is superseded by
 iwlwifi which doesn't require one.)

 The two patches below start a new release in jaunty-lrm and add a
 postinst snippet to remove this conffile if it wasn't modified, or
 rename it out of the way if it was.  You can also get the patches from:
    git://kernel.ubuntu.com/lool/ubuntu/ubuntu-jaunty-lrm.git

 I did a test build and installed the new
 linux-restricted-modules-common which removed the conffile on one of my
 systems.

   Cheers,
