Fixed compiler warning in v-boot reference.

The error was:
  arch/arm/lib/crossystem_arch.c: In function ‘VbReadSharedMemory’:
  arch/arm/lib/crossystem_arch.c:134: error: format ‘%d’ expects type ‘int’, but argument 5 has type ‘long unsigned int’

BUG=none
TEST=(outside choot): cd src/platform/vboot_reference; make
