build: Fix Build.gn with Graph.DebugInfo (KhronosGroup#6688)

KhronosGroup#6666 (comment)
is breaking the `build.gn` for VVL... I just grabbed the commit before,
so VVL is good

I tried to copy-and-paste a fix, zero idea how to actually test it, but
seems like it should work for someone who knows GN better
