libowfat: update to version 0.34

changes since 0.33:
 * be more C99 compliant (Florian Weimer)
 * add C++ convenience overloads to uint*.h
 * remove unaligned memory access behind #ifdef i386 from uint*.h
   (compilers are now smart enough so they are no longer needed and they
   were technically undefined behavior so the sanitizer complained)

OpenWrt package changes:
 * The newly introduced 'json' build tool is added to the host build and
   staged as 'libowfat-json'.
 * DEBUG option is now set by global CONFIG_DEBUG option
 * fixed duplicate CROSS prefix of RANLIB
