Add a mechanism to ignore a fake in call history.

[CanadianHoser]

Is your feature request related to a problem? Please describe.
Mocking a large function, with a nested loop of calls to a faked out function, I've surpassed the call-history length. As a result, I can't check the call history for some of the latter functions.

Describe the solution you'd like
I'd like to be able to specify fff ignore certain functions in the call history log.

Describe alternatives you've considered
I can set FFF_ARG_HISTORY_LEN, but this is difficult to maintain if the number of fake calls increase.

Additional context
None.
