tools: kwbimage: Simplify aligning and calculating checksum

The return value of kwbimage_generate() is used for aligning the data
part of kwbimage. Use it for calculating proper 4 byte alignment as is
required by BootROM and also use it for allocating additional 4 bytes
for the 32-bit data checksum.

This simplifies the alignment code to be only at one place (in function
kwbimage_generate) and also simplifies setting checksum as it can be
directly updated in memory.
