scanner: use separate guards for validator functions

Generated XXX_is_valid() functions for enums are guarded behind the
same #define as the enum itself. This worked fine until recently,
but since fbd7460737c9 ("scanner: add new enum-header mode") we're
also generating enum-only headers.

When including the enum-only header first, and then the server
header, the validator functions are missing.

Define a separate guard to fix this.
