challenge: tolerate strings instead of struct in FP payload

[blotus]

Fixes #4654

Now, all structs in the fingerprint have a custom unmarshaler that handles the source attribute being either a string or the actual type (similarly to FlexInt/FlexBool) as fpscanner will sometimes return ERROR instead of the actual struct.

If a string is returned, we will simply use the empty value of the struct.
