[PWGCF,PWGLF] Drop the redundant ignore-overflows argument from binning policies

The trailing true passed to ColumnBinningPolicy and FlexibleBinningPolicy is
the constructor's own default, so removing it changes nothing here.

It matters because O2 is dropping that parameter: the policies always map
values outside the outermost axis edges to bin -1 now, and selecting the
alternative per instance is going away. Nothing in O2Physics ever passed
false, but twelve sites spelled the default out and would stop compiling,
since these are braced initialisations against a user-declared constructor
with no aggregate-init fallback. Removing the argument first lets the tasks
build against O2 both before and after that change.

In twoParticleCorrelationsMpi the comment explaining the argument goes with
it, keeping only the part that stays true: out-of-range collisions get bin -1.
