Fix

- Set `vm.mmap_min_addr=0` in the `--privileged` container before the
  chroot. [Mingyang Li]

  `sqv` (the ARM OpenPGP verifier used by apt) needs to mmap at address `0x1000`, but `vm.mmap_min_addr` is too high.
- Mount `proc` and `sys` AFTER the first stage of debootstrap. [Mingyang
  Li]
- UID reference in `override.sh`. [Mingyang Li]

  `sudo -u#1000` requires UID 1000 to exist in passwd, but the build container only has `root`. Fixed by replacing those two `sudo -u#1000 -g#1000 mkdir -p` calls with `install -d -o 1000 -g 1000 -m 0755` in override.sh.
