fix: normalize username and UID in build settings fixture

The show-build-settings fixture had hardcoded username and UID values
that would cause test failures on other developer machines. Added
normalizer rules for ALTERNATE_OWNER, INSTALL_OWNER, USER,
VERSION_INFO_BUILDER, and UID build settings.
