Subject: [PATCH net-next 1/2] tools: ynl-gen: don't output external constants

A definition with a "header" property is an "external" definition
for C code, as in it is defined already in another C header file.
Other languages will need the exact value but C codegen should
not recreate it. So don't output those definitions in the uAPI
header.
