61e964457d stupidgcm: fix openssl 1.1 build failure 
Fixed by including the correct header. Should work on older openssl
versions as well.

Error was:
locking.go:21: undefined reference to `CRYPTO_set_locking_callback'

cf29ce3762 stupidgcm: set dummy locking callback. 
In general, OpenSSL is only threadsafe if you provide a locking function
through CRYPTO_set_locking_callback. However, the GCM operations that
stupidgcm uses never call that function.

To guard against that ever changing, set a dummy locking callback
that crashes the app.
