Bump dataprivacy plugin version to a higher number

As found out by David Mudrák (@mudrd8mz) in MDL-63292:

The $plugin->version was not raised when tool_policy was integrated into core in MDL-62800. I think it should be increased so that

the versions in the plugins directory will always and forever have lower version number that the ones in the standard distribution, and
we have a reserve in the CONTRIB to still eventually increase the version number, should we need it.
I found this because I was thinking of adding a new version 2017111312 to the plugins directory that would display a warning if it finds itself running on the Moodle version released on 10 September.

Same applies to tool_dataprivacy.
