Fix Superuser on 64 bits target

 - An export to "/system/lib" is not required and cause problems
   as this is a 32 bits lib dir only
 - When writing to socket, datatype size_t was used, which is
   4 bytes on 32 bits target and 8 bytes on 64 bits.
   Superuser expects it as a 4 bytes length. So, it was
   replaced by "uint32_t" datatype
