accounts: Delete duplicate entries.
When adding multiple instances of a service requiring some user account/group, we could end up with multiple entries for that account or group in /etc/passwd or /etc/group. * gnu/build/accounts.scm (database-writer)[write-entries]: Add call to 'delete-duplicates'. * tests/accounts.scm ("write-passwd with duplicate entry"): New test.
