It's trying to open /etc/sv/cron/supervise/ok (from /etc/sv/cron),
and gets redirected to absolute path (that's the '/' magic retry, see
documentation of FS_RETRY_MAGICAL) /run/runit/supervise/cron/ok.

It then tries to open it, but gets redirected to relative path
runit/supervise/cron/ok (I guess that on your machine /run is a
tmpfs mount?)

It tries to open it, but apparently no process is actually listening on
it.
Maybe try without /run being a tmpfs: in
/usr/lib/init/mount-functions.sh in mount_run put an exit 0 just after
read_fstab.
