Oilpan: Don't limit the number of wrappers collected in minor GC cycles

In Oilpan, it is better to not limit the number of wrappers collected in
minor GC cycles. This may increase the pause time of a minor GC,
but if we give up collecting wrappers in a minor GC, it will instead end up
with increasing the cost of subsequent Oilpan's GCs. Thus it will be better
to collect as many wrappers as possible for minimizing the value of
max(a pause time of a minor GC, a pause time of Oilpan's GC).
