fix: increase log rotator line scan limit

In case where gelf/json logging is used, its fairly easy to exceed the 16k limit, resulting in json output being cut up into multiple strings the result is invalid json lines which can create all kind of badness in the logging server This fixes hashicorp#4699 Signed-off-by: Christian Winther <[email protected]>
