The local fs backend driver tests require that a dummy file is
created on the host side before running the xattr limit tests,
otherwise the test will fail because the file is expected to exist.

The original call of g_file_set_contents() didn't check its
return value, which might cause subsequent test checks to fail,
making it harder to identify the root cause.

Fix this by simply wrapping the call into a g_assert().

driver)")
