Benny Halevy f5ffd5fc5f sstables: Fix reactor stall in sstables::seal_summary() ...

With relatively big summaries, reactor can be stalled for a couple
of milliseconds.

This patch:
a. allocates positions upfront to avoid excessive reallocation.
b. returns a future from seal_summary() and uses `seastar::do_for_each`
to iterate over the summary entries so the loop can yield if necessary.

Fixes #7108.
