Fix ioctl(fd, PROCMAP_QUERY, ...) so that valgrind correctly considers memory referenced by vma_name_size and vma_name_addr members of struct procmap_query as initialized by ioctl(). Extend ioctl syscall wrappers with needed PRE_MEM_WRITE() and mainly POST_MEM_WRITE(). Add a testcase. https://bugs.kde.org/show_bug.cgi?id=508328
