Patch install.py directly to exclude MariaDB-server from dnf commands

- Patches install.py (not just wrapper script) to add --exclude=MariaDB-server*
- Handles both shell commands and Python string commands
- Ensures MariaDB exclude is applied to all installation commands
- Works in conjunction with dnf.conf excludes
