Subject: [PATCH] install: Generate InstallScripts.json in consistent location

Since commit 159ba027b9 (Install: Add parallel installation option,
2024-06-19, v3.31.0-rc1~333^2) the file was generated relative to the
current working directory.  This is not always the top of the build
tree, so specify the path explicitly.
