Open file cache: disable_symlinks with open_file_cache_events.

Previously, different disable_symlinks settings were respected when
retrieving a file from open file cache when using periodic retest, but
were ignored with using open_file_cache_events.

Fix is to test disable_symlinks settings in all cases, and retest the
file if requested settings are different from what we already have in
the cache.
