All tracked .sh files were stored as mode 100644 (non-executable), even

Bash equivalent of the PowerShell test change. Also relaxes the platform
dry-run assertion to match on "-$platform" instead of "-$platform/", since
the installer now reports one destination summary line per sync instead of
one line per copied file.
