add remote-fs.target to tomcat_lk.service After= dependency

Fixes a race condition where tomcat_lk.service starts before the EFS
mount is ready after a system reboot. The nightly update script
(lk-ssm-update.sh) reboots the server after installing new binaries;
on boot, systemd was starting LabKey before the NFS/EFS mount at
/mnt/efs_volume was available, leaving the /labkey/labkey/files symlink
broken and causing LabKey to abort with "Invalid site root does not exist".

Adding remote-fs.target to After= ensures systemd waits for all _netdev
remote filesystem mounts before starting the service.
