fix(inputs.sqlserver): Honor timezone on backup metrics

[Grosoiu]

We have been testing the sql server input in monitoring our production server and for the last_full_backup/last_differential_backup/last_log_backup we can see that if the timezone is different than UTC on the server, the time is not displayed properly. By adding the timezone offset in the query, we have removed the issue.

@Trovalo - this sounds like the right thing to do, but could you double check as well? Thanks!
