[advapi32/tests 1/3] Add some ClearEventLog tests

[Paul Vriens-2]

Hi,

I'm not clearing a real eventlog. This will happen in later patches when
we create our own.

Added a helper for creating a backup eventlog as the same piece of code
is going to be used several times.

Changelog
   Add some ClearEventLog tests

Cheers,

Paul.
