nixos/tests/prometheus: remove invalid thanos config flag

Upstream has apparently changed the configuration format and is now
throwing an error when the `encrypt_sse` option is set. According to the
current version of the documentation encryption moved to the
`sse_config` option that (is optional and) offers all the features we do
not use or care about for this test.
