tests/unit/crypto-tls-x509-helpers: deinit privkey in test_tls_cleanup

Browse Source 
We create a gnutls_x509_privkey_t in test_tls_init(), but forget
to deinit it in test_tls_cleanup(), resulting in leaks
reported in hte migration test such as:

Indirect leak of 8 byte(s) in 1 object(s) allocated from:

(Oddly, there is no reported leak in the x509 unit tests, even though
those also use test_tls_init() and test_tls_cleanup().)

Deinit the privkey in test_tls_cleanup().
