initramfs-tools hook script should not complain to stdout

[Jae-hyeon Park]

Binary package hint: tuxonice-userui

The script /usr/share/initramfs-tools/hooks/tuxonice_userui echoes error (or warning) messages to stdout if it does not find TuxOnIce user interface from the running kernel. This can break installation of a kernel package built by make-kpkg. The error message from dpkg -i looks like:

    User postinst hook script [update-grub] exited with value 20
    dpkg: error processing linux-image-2.6.31.4-tuxonice (--install):
     subprocess installed post-installation script returned error exit status 128
    Errors were encountered while processing:
     linux-image-2.6.31.4-tuxonice

This can be fixed by adding ">&2" at the end of each echo command that prints an error message.
