It turns out that this failure is triggered by the presence of
py3-cryptodome.

Removing py3-cryptodome on sparc64 makes all tests pass. For both
tlslite-ng and tlsfuzzer. Since a ton of stuff pulls in py3-cryptodome
via gobject-introspection, I think we had better work around this, as it
will break all RSA operations.

With the patch below all tests for tlslite-ng and tlsfuzzer pass
independently of whether py3-cryptodome is present. Tested on both
sparc64 and amd64.

ok? or do you have a better suggestion?
