tests/external_override: Add override test for internal implementations

Browse Source 
This adds a test to check if the internal implementation is not used
when it is not supposed to be used.

To be able to override functions using LD_PRELOAD, a shared version of
the torture library was added, as well as a shared library for each
of the algorithms implemented internally (ChaCha20, Poly1305,
curve25519, and ed25519).
