tests: add varints_bitpatterns test
The current tests for varint only check that
serialization-deserialization is a roundtrip. That is a useful test, but
it is also good to check for some exact bit patterns, to prevent a code
change that changes the serialization format from going undetected.
As the varint functions are templated, also check with different types.
