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

Lots of test cases were written to use hardcoded /tmp directory for
temporary files. To avoid this, we update them to use g_dir_make_tmp()
or g_file_open_tmp() when appropriate.

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

Changes in v2:
- Use g_dir_make_tmp(), g_file_open_tmp() when appropriate

Whenever introducing g_auto* usage, please make sure to initialize the
variable to NULL or a correct value.

Why not use g_auto here?

You'll need to replace "return template" with "return
g_steal_pointer(&template)")

I suggest splitting this patch for the various tests.
