vm: Compute UUIDs truly deterministically.
This is a followup to 1540075c790dfaeff52c93392f2fc63b9e23b77e. The mistake had no effect on prior Guile versions but it's visible since Guile 3.0.1 and the fix for <https://bugs.gnu.org/39634>. * gnu/system/vm.scm (operating-system-uuid): Hash a list of 'file-system-digest' values, not the 'file-system-type' procedure.
