Remove HAVE_WORKING_LINK
Previously, hard links were not used on Windows and Cygwin, but they
support them just fine in currently supported OS versions, so we can
use them there as well.
Since all supported platforms now support hard links, we can remove
the alternative code paths.
Rename durable_link_or_rename() to durable_rename_excl() to make the
purpose more clear without referencing the implementation details.
