kexec-zImage-arm: simply cmdline-related DTB resizing
When resizing a dtb to add the command-line, only resize the DTB once,
rather than once to add the /chosen node, and once to add the bootargs
property.
Also, simply add 1K of overhead (beyond strlen(cmdline)) to the buffer,
to avoid requiring precise knowledge of the size impact of the requested
FTB changes. In particular, some padding is performed when setting
property values, which was not accounted for in the current code, which
caused failures to set the bootargs values in some cases.
