pg_basebackup pg_receivexlog: Issue fsync more carefully

Several places weren't careful about fsyncing in the way.  See 1d4a0ab1
and 606e0f98 for details about required fsyncs.

This adds a couple of functions in src/common/ that have an equivalent
in the backend: durable_rename(), fsync_parent_path()
