Fix improper "already mounted" errors with ZFS

The obvious approach for using ZFS and ecryptfs together involves
creating a dataset like this:
zfs create -o mountpoint=/home/.ecryptfs/USER rpool/home/USER

As a result, /proc/mounts looks like this:
rpool/home/USER /home/.ecryptfs/USER zfs rw,xattr 0 0

ecryptfs-setup-private checked for existing mount points using a grep
which was effectively left-anchored. Unfortunately, this can match the
device column. A space at the beginning of the pattern corrects this.

I applied the same fix to the CRYPTDIR for consistency and correctness,
though I do not believe it was a practical problem in the same way.
