Use = instead of deprecated : as security option separator (#3167)

Docker reports:
Sep 23 08:16:31 homeassistant dockerd[467]: time="2021-09-23T08:16:31.771717436Z" level=warning msg="Security options with `:` as a separator are deprecated and will be completely unsupported in 17.04, use `=` instead."

Since it seems that Docker supports `=` since quite a while, we should
use `=` only.
