  wrong /dev/pts owner for login shell (and $HOME)

Bug description:
  sudo-rs doesn't set a login shells /dev/pts owner correctly and
  doesn't set its $HOME, while sudo.ws does.

  sudo.ws:

  jj at host % lxc exec canonical -- sudo.ws -i -u ubuntu
  ubuntu at canonical ~ % pwd
  /home/ubuntu
  ubuntu at canonical ~ % echo $HOME
  /home/ubuntu
  ubuntu at canonical ~ % tty
  /dev/pts/4
  ubuntu at canonical ~ % ls -la /dev/pts/4
  crw--w---- 1 ubuntu tty  136, 4 Nov 12 15:37 4

  sudo-rs:

  jj at host % lxc exec canonical -- sudo-rs -i -u ubuntu
  canonical% pwd
  /home/ubuntu
  canonical% echo $HOME
  /root
  canonical% tty
  /dev/pts/4
  ubuntu at canonical ~ % ls -l /dev/pts/4
  crw--w---- 1 root tty  136, 4 Nov 12 15:28 4

  two bugs in sudo-rs:
  - pty owner is wrong (should be the login user, not root)
  - HOME is not set (it is in env_keep) (and it works with: lxc exec canonical -- sudo-rs HOME=/home/ubuntu -i -u ubuntu)

  correct pty owning is important, otherwise e.g. gpg-agent can't show
  pinentry on the terminal where gpg was invoked on!
