Trivial build cleanup

[Adam Litke]

I was getting annoyed with all the junk printed when generating the
zImage so I converted the noisy commands over to the kbuild quiet_cmd
framework.  I was able to suppress the output of the imagesize.c target
but not in the normal way due to shell escaping issues.  Comments?
