rv: Add KUnit mock for current

Some monitors do not only rely on tracepoint arguments but also on the
currently executing task.
This makes it more challenging to mock events in KUnit.

Define wrapper functions around current, the functionality is mocked
only during KUnit, an additional function call is avoided using a static
branch unless any (even unrelated) KUnit test is running.

Rely on a global mock_current variable that is set only by the RV KUnit
tests and cleared on teardown. Unrelated KUnit tests that happen to
trigger RV handlers would see it null and use current.

rv: Use generic rv_this for the rv_monitor variable in LTL

Align the rv_monitor variable name in LTL to the generic rv_this as it
is already done for DA/HA monitors. This improves consistency and eases
assumptions across model classes.
