[dm-crypt] mounting luks-encrypted external drive without root access

I think giving that user access permissions (file permissions) 
to the drive should be enough. Best done via a special
group and adding the user to that group.

Alternative is a suid binary or script. That is basically
what is done for fstab, i.e. /bin/mount runns as su-root.
