[PATCH v3 08/54] tests/qtest: cxl-test: Avoid using hardcoded /tmp

[Bin Meng]

From: Bin Meng <bin.meng@windriver.com>

This case was written to use hardcoded /tmp directory for temporary
files. Update to use g_dir_make_tmp() for a portable implementation.

Signed-off-by: Bin Meng <bin.meng@windriver.com>

Changes in v3:
- Split to a separate patch
- Ensure g_autofree variable is initialized
