Benny Halevy 1c26d49fba database_test: test_truncate_without_snapshot_during_writes: apply mutation on the correct shard ...

Currently, all the mutations this test generates are applied on shard 0.
In rare cases, this may lead to the following crash, when the flushed
sstable doesn't contain any key that belongs to the current shard,
as seen in https://jenkins.scylladb.com/job/releng/job/Scylla-CI/1390/artifact/testlog/x86_64/dev/database_test.test_truncate_without_snapshot_during_writes.114.log

```

Instead, generate random keys and apply them on their
owning shard, and truncate all database shards.

Fixes #11076
