Revert recent changes with durable_rename_excl()

Browse Source 
This reverts commits 2c902bb and ccfbd92.  Per buildfarm members
kestrel, rorqual and calliphoridae, the assertions checking that a TLI
history file should not exist when created by a WAL receiver have been
failing, and switching to durable_rename() over durable_rename_excl()
would cause the newest TLI history file to overwrite the existing one.
We need to think harder about such cases, so revert the new logic for
now.

Note that all the failures have been reported in the test
025_stuck_on_old_timeline.
