Update sd-devices test to check for udisks2, not cryptsetup

[rocodes]

Status

Ready for review

Description of Changes

Now that udisks2 is used for locking/unlocking export devices, update sd-devices vm test.
Refs freedomofpress/securedrop-client#1777

Testing

visual review, ci passes. udisks2 is already installed on sd-devices by default, but otherwise this would not be expected to pass until updated packages and their dependencies were installed on the target sdw machine.

Deployment

n/a

Nice - just saw this (using the new CI!!) and wondered what it was about :)

Good catch! @rocodes, I'll approve but defer to you for merge, given the order of operations before release.

Verified by sdw-ci :)
