Build external override library with all symbols

Browse Source 
The curve25519 depends on ssh_get_random, which is normally built into libssh.
For the external override tests to build, we need to have them in separate
source file that can be included for this test.

For some reason, this did not happen on CI builds, but it did happen in koji
during RPM builds.
