tools/kwbimage: Fix compilation warning

This patch fixes a compilation warning of kwbimage.c:

tools/kwbimage.c: In function ‘kwbimage_set_header’:
tools/kwbimage.c:784:8: warning: ‘headersz’ may be used uninitialized in this function [-Wmaybe-uninitialized]
  memcpy(ptr, image, headersz);
        ^
Instead of using multiple if statements, use a switch statement with
a default entry. And return with error if an unsupported version
is configured in the cfg file.
