FYI, my system originally only had udisks2 installed, not udisks. I
installed udisks (so that both are now installed) and rebooted, and the
swap device is now set up properly.

udevadm info now says,

        P: /devices/virtual/block/dm-0
        N: dm-0
        L: 50
        S: disk/by-id/dm-name-swap0
        S: disk/by-id/dm-uuid-CRYPT-PLAIN-swap0
        S: disk/by-uuid/02331091-93b9-46e3-827b-4d940df2159e
        S: mapper/swap0
        E: DEVLINKS=/dev/disk/by-id/dm-name-swap0 /dev/disk/by-id/dm-uuid-CRYPT-PLAIN-swap0 /dev/disk/by-uuid/02331091-93b9-46e3-827b-4d940df2159e /dev/mapper/swap0
        E: DEVNAME=/dev/dm-0
        E: DEVPATH=/devices/virtual/block/dm-0
        E: DEVTYPE=disk
        E: DM_NAME=swap0
        E: DM_STATE=ACTIVE
        E: DM_SUSPENDED=0
        E: DM_TABLE_STATE=LIVE
        E: DM_TYPE=raid
        E: DM_UDEV_PRIMARY_SOURCE_FLAG=1
        E: DM_UDEV_RULES=1
        E: DM_UUID=CRYPT-PLAIN-swap0

        E: ID_FS_VERSION=2
        E: MAJOR=254
        E: MINOR=0
        E: SUBSYSTEM=block
        E: TAGS=:systemd:
        E: UDISKS_DM_TARGETS_COUNT=1

        E: UDISKS_DM_TARGETS_TYPE=crypt
        E: UDISKS_PRESENTATION_NOPOLICY=1
        E: USEC_INITIALIZED=24880
        E: net.ifnames=1

i.e., SYSTEMD_READY is no longer there, which I believe implicitly means
that it's set to 1.
