certgen: Use t.TempDir in tests.

davecgh · davecgh · commit ecc32f7dcccc · 2025-02-18T09:38:58.000-06:00
This update the test code to make use of the testing.TempDir method
introduced in Go 1.15 to ensure the temporary directories are
automatically removed when the associated tests and all of their
subtests complete.
