handler: refact check_socket_non_container

the `stat --printf=%n` returns something like following:

```
ok: [osd0] => changed=false
  cmd: |-
    stat --printf=%n /var/run/ceph/ceph-osd*.asok
  delta: '0:00:00.009388'
  end: '2020-10-06 06:18:28.109500'
  failed_when_result: false
  rc: 0
  start: '2020-10-06 06:18:28.100112'
  stderr: ''
  stderr_lines: <omitted>
  stdout: /var/run/ceph/ceph-osd.2.asok/var/run/ceph/ceph-osd.5.asok
  stdout_lines: <omitted>
```

it makes the next task "check if the ceph osd socket is in-use" grep
like this:

```
ok: [osd0] => changed=false
  cmd:
  - grep
  - -q
  - /var/run/ceph/ceph-osd.2.asok/var/run/ceph/ceph-osd.5.asok
  - /proc/net/unix
```

which will obviously fail because this path never exists. It makes the
OSD handler broken.

Let's use `find` module instead.
