This caused scanelf to crash under seccomp sandbox. The change whitelists 'statx' syscall.

We probbaly need to add 'statx' to sandbox: # strace -f scanelf -T /usr/bin/ execve("/usr/bin/scanelf", ["scanelf", "-T", "/usr/bin/"], 0xffe0e7ec /* 32 vars */) = 0 ... statx(AT_FDCWD, "/usr/bin/", AT_STATX_SYNC_AS_STAT|AT_SYMLINK_NOFOLLOW, STATX_BASIC_STATS, <unfinished ...>) = ? +++ killed by SIGSYS (core dumped) +++ Bad system call
