Revert "Revert "Add --kloadaddr option to utilities""

This reverts commit bc7a84d9a1bef3fb8c1e2709033f6c9777599fe9.

It was a false alarm that --kloadaddr causes chromeos-install on a
x86 targets to fail. The error of chromeos-install cannot be
reproduced, and judging by the reported error message, the error
should not be attributed to --kloadaddr, which has no effect in x86
targets. So --kloadaddr is restored.

Verification process are below:

(Verify that --kloadaddr option is restored)
$ dump_kernel_config -h
Expected argument after options
dump_kernel_config - Prints the kernel command line

Usage:  dump_kernel_config [--kloadaddr <ADDRESS>] <image/blockdevice>

(Setup a x86 target with kernel-next profile)
$ rm -rf /build/${X86_TARGET}
$ ./setup_board --board=${X86_TARGET} --profile=kernel-next
$ ./build_packages --board=${X86_TARGET}
$ ./build_image --board=${X86_TARGET}

(Run chromeos-install on target machine successfully)
$ /usr/sbin/chromeos-install

(Change directory to where image sits)
$ cd ~/trunk/src/build/images/${X86_TARGET}/latest

(Unpack Chromium OS image)
$ ./unpack_partitions.sh chromiumos_image.bin

(Verify that dump_kernel_config runs successfully)

I have not look at this again- but you have an LGTM. Happy to help if
needed. - Simon
