Subject: [PATCH] Extract: retain times for symlinks

Original report by Pat Riehecky at
https://bugzilla.redhat.com/1486364

* src/copyin.c (copyin_device): Don't check for retain_time_flag
global, it's done by set_file_times.
(copyin_link): Call set_file_times to restore symlink times.
* src/util.c (set_perms): Don't check for retain_time_flag global,
done by set_file_times call.
(set_file_times): Do nothing if retain_time_flag global is false.
* src/copypass.c (process_copy_pass): Call set_file_times for
symlinks.
