include: don't mention stub headers more than once in a make rule

When !GRANT_TABLE and !PV_SHIM headers-n contains grant_table.h twice,
causing make to complain "target '...' given more than once in the same
rule" for the rule generating the stub headers. We don't need duplicate
entries in headers-n anywhere, so zap them (by using $(sort ...)) right
where the final value of the variable is constructed.

Fixes: 6bec713f871f ("include/compat: produce stubs for headers not otherwise generated")
