Revert of Fix the Copresence permission. (patchset #1 of https://codereview.chromium.org/523433002/)

Reason for revert:
This change causes a test failure:

http://build.chromium.org/p/chromium.chromiumos/builders/Linux%20ChromiumOS%20Tests%20%281%29/builds/48008/steps/unit_tests/logs/stdio

Error:

[ RUN      ] PermissionsTest.PermissionMessages
../../chrome/common/extensions/permissions/permission_set_unittest.cc:781: Failure
Value of: permission_info->message_id()
Actual: 65
Expected: PermissionMessage::kNone
Which is: 1
unexpected message_id for copresence

Looks like this change is the cause.

Original issue's description:
> Fix the Copresence permission.
>
> The initializer for the Copresence permission is malformed. It specifies the
> message id instead of the flag.
