powerpc fix installation of images

"The problem is that (a) the kernel's postinst uses debconf, which uses
stdin and stdout for communication and forbids other junk from appearing
there, and (b) the kernel's postinst calls update-initramfs, which
outputs status information to stdout which debconf thinks is a command
in its protocol and thus confuses any future real debconf commands.
Since the kernel's postinst is the thing with special requirements due
to using debconf, it should be the thing responsible for redirecting
file descriptors around as necessary." -cjwatson
