  capabilities set with setcap are not honoured

Bug description:
  Hi,

  In Ubuntu 19.10 I set capabilities as;

  setcap cap_net_admin,cap_sys_admin+ep /bin/ip
  getcap /bin/ip
  /bin/ip = cap_net_admin,cap_sys_admin+ep

  but;

  > ip addr add 20.20.20.20/32 dev lo
  RTNETLINK answers: Operation not permitted

  *exactly* the same works perfect on 18.04.3 LTS.

  BTW the set of a silly address on "lo" is just an example.
  Nothing works on Ubuntu 19.10
