Cause: tempdir path is not defined in check mode, and __selinux_item.path may be undefined
in some cases.

Consequence: The role will give an error when running in check mode that various
variables are undefined.

Fix: Skip tasks that require tempdir.path to be defined. Handle cases where variables
may be undefined.

Result: The role works in check mode.

1. 1. Summary by Sourcery

Enable Ansible check mode support in selinux_load_module by guarding against undefined tempdir.path and __selinux_item.path.

Bug Fixes:

• Guard copy, install, and cleanup tasks against undefined tempdir.path to prevent errors in check mode
• Provide a default for __selinux_item.path when copying modules to avoid undefined path errors

Enhancements:

• Skip filesystem operations requiring tempdir.path when it is not defined to improve check mode compatibility
