Benny Halevy 35d89298da test: commitlog_test: test_allocation_failure: fill memory using smaller allocations ...

commitlog was changed to use fragmented_temporary_buffer::ostream (db::commitlog::output).
So if there are discontiguous small memory blocks, they can be used to satisfy
an allocation even if no contiguous memory blocks are available.

To prevent that, as Avi suggested, this change allocates in 128K blocks
and frees the last one to succeed (so that we won't fail on allocating continuations).

Fixes #8028
