Fix stack-use-after-scope in dns_message_checksig test

Browse Source 
Previously stack with buffer for test dns message went out of scope
before the message was processed. For fuzz testing its better to avoid
allocation, so let's avoid allocations completely and use simplest
possible static buffer.

Fixes: #3565
