largefiles: always consider updatelfiles 'checked' parameter set
mergeupdate already set the flag to update all. This will thus only change
overriderevert and scmutilmarktouched ... where the flag effectually also were
true. The test coverage thus shows no change.
As the flag always is set, it is removed.
This is mainly a change for keeping the code simple and consistent and correct,
but it should also make it faster in many cases.
