Subject: [PATCH 1/2] test: add tests for append_line_once function

Added missing tests to `tests/run-tests.sh` to thoroughly cover the
`append_line_once` bash function defined in `lib/linux/install.sh`.
Specifically, tests were added to verify that it formats appended content
correctly (joining multi-word strings and adding the AutoOS header), prevents
duplicate additions on subsequent calls (idempotency), and correctly creates
missing parent directories.
