Make objectives of Summaries explicit

With the next release of client_golang, Summaries will not have
objectives by default.

As it turns out, for prometheus_tsdb_head_gc_duration_seconds and
prometheus_tsdb_wal_truncate_duration_seconds, the objective-less
default makes more sense then the current default.

To make sure we do the right thing before and after the upcoming
release of client_golang, I have set the objectives explicitly
wherever that was not the case so far:

- prometheus_tsdb_head_gc_duration_seconds and
  prometheus_tsdb_wal_truncate_duration_seconds now have no objectives
  explicitly.
- prometheus_tsdb_wal_fsync_duration_seconds now explicitly uses the
  previous default objectives.
