New hwclock.sh for powerpc

[Joel Klecker <jk@espy.org>]

I worked this script out to address the problem we have on powerpc 
with the different hardware clock programs.
This should use `clock' on Power Macs and `hwclock' on CHRP.
Please test it so I can add it to 'powerpc-utils' if it works.

For those who care, my plan is to have powerpc-utils divert the 
hwclock.sh that util-linux installs.

(I suggest renaming the old /etc/init.d/hwclock.sh out of the way 
before copying this one in its place.)
