The _sysconfig_vars__linux_x86_64-linux-gnu.json file contains a "userbase" field that is populated from the build host user's $HOME at build time. This leaks the build host user's home directory path into the target rootfs.
The existing py_package_preprocess() cleanup for this JSON file only strips known OE build path prefixes (STAGING_DIR_TARGET, RECIPE_SYSROOT, etc.), but the userbase value comes from the build user's $HOME environment variable which doesn't match any of those patterns. Set userbase to an empty string in the packaged JSON. This is safe because at runtime, sysconfig.get_config_vars() always recomputes userbase by calling _getuserbase(), which resolves the actual target user's ~/.local path dynamically. The static value in the JSON is never used for runtime path resolution.
