Fix mkdirs.sh install errors on replica servers
When you run the mkdirs.sh script on an edge server, you get a symlink error for the checkpoints directory:
Running: ln -s /tmp/hxmounts/hxdepots/p4/1/checkpoints.edge.1 /tmp/p4/1/checkpoints.edge.1
ln: failed to create symbolic link ‘/tmp/p4/1/checkpoints.edge.1’: No such file or directory
Error: (line: 735) Failed to create symlink.
You also get an error for the chown commands on the checkpoints directory because there is an extra / slash in the path.
