Adding functionality to allow for rebuilding of vmlinuz after it
has been processed into vblock and header stripped. Basically appends
the 16-bit header of a vmlinuz image onto the end of the vblock.
BUG=chromium:438302
BRANCH=none
TEST=Successfully ran "make runalltests".
Also, ran:
1. Repack kernel block (so that 16-bit header is included):
"vbutil_kernel --pack kern_0 ..."
2. Verify kernel: "vbutil_kernel --verify kern_0 ... ". This should
be done before booting into kernel, but not necessary for it to work.
3. Rebuild vmlinuz image:
"vbutil_kernel --get-vmlinuz kern_0 --vmlinuz-out vm.out"
4. Set up kexec with vmlinuz (this should complete with no errors):
"kexec -l vm.out (other kernel cmd line args)"
5. Boot into kernel:
"kexec -e"
