[net-next] selftests/tls: fix selftest with CHACHA20-POLY1305

[Vadim Fedorenko]

TLS selftests were broken also because of use of structure that
was not exported to UAPI. Fix by defining the union in tests.

Fixes: 3502bd9b5762 (selftests/tls: fix selftests after adding 
ChaCha20-Poly1305)
Fixes: 4f336e88a870 (selftests/tls: add CHACHA20-POLY1305 to tls selftests)
