[PATCH] tests/qtest/migration: Only build tls_no_hostname test with TASN1

The test_precopy_tcp_tls_no_hostname test and its start hook use
TestMigrateTLSX509 and migrate_hook_start_tls_x509_common(), which
are only defined when CONFIG_TASN1 is set. This means building with
gnutls enabled but libtasn1 unavailable fails:

  ../tests/qtest/migration/tls-tests.c: In function 'migrate_hook_start_tls_x509_no_host':
  ../tests/qtest/migration/tls-tests.c:510:5: error: unknown type name 'TestMigrateTLSX509'

Guard the test with CONFIG_TASN1 like the other x509 tests.

Fixes: df9c38b19af8 ("tests/qtest/migration: Add a NULL parameters test for TLS")
