tools: ynl-gen: use macro for binary min-len check

Browse Source 
This patch changes the generated min-len check for binary
attributes to use the NLA_POLICY_MIN_LEN() macro, thereby the
generated code supports strict policy validation.

With this change TypeBinary will always generate a NLA_BINARY
attribute policy.

This doesn't change any currently generated code, as it isn't
used in any specs currently used for generating code.
