sudo: allow transmitting SIGWINCH to its child 
When resizing the X11 window of a terminal running sudo on a remote
Debian 10 system (through ssh), sudo forwards SIGWINCH to its children
(this behavior might be caused by using "Defaults use_pty" in
/etc/sudoers). This leads to the following audit logs:

    type=AVC msg=audit(1567880108.988:13823): avc:  denied  { signal }
    for pid=15670 comm="sudo" scontext=sysadm_u:sysadm_r:sysadm_sudo_t
    tcontext=sysadm_u:sysadm_r:sysadm_t tclass=process permissive=0

    type=SYSCALL msg=audit(1567880108.988:13823): arch=c000003e
    syscall=62 success=no exit=-13 a0=ffffc2c9 a1=1c a2=ffffffff a3=100
    items=0 ppid=15607 pid=15670 auid=1000 uid=0 gid=0 euid=0 suid=0
    fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts6 ses=721 comm="sudo"
    exe="/usr/bin/sudo" subj=sysadm_u:sysadm_r:sysadm_sudo_t key=(null)

    type=PROCTITLE msg=audit(1567880108.988:13823):
    proctitle=2F7573722F62696E2F7375646F002D73

The process tree (ps -ef, edited) on this remote system was:

    LABEL                           UID    PID  PPID  TTY   CMD
    system_u:system_r:sshd_t        user  15519 15480 ?     sshd: user@pts/5
    sysadm_u:sysadm_r:sysadm_t      user  15524 15519 pts/5 -zsh
    sysadm_u:sysadm_r:sysadm_sudo_t root  15607 15524 pts/5 /usr/bin/sudo -s
    sysadm_u:sysadm_r:sysadm_sudo_t root  15670 15607 pts/6 /usr/bin/sudo -s
    sysadm_u:sysadm_r:sysadm_t      root  15671 15670 pts/6 /usr/bin/zsh

The denied syscall was:

* syscall=62: int kill(pid_t pid, int sig)
* a0=ffffc2c9: pid = -15671 (process group of sudo's child)
* a1=1c: sig = 28 = SIGWINCH

Allow such a signal to be transmitted.
