libssh: ignore deprecation warnings

libssh 0.10.0 marks all SCP functions as "deprecated" which causes
compiler warnings and errors in our CI jobs and elsewhere. Ignore
deprecation warnings if 0.10.0 or later is found in the build.

If they actually remove the functions at a later point, then someone can
deal with that pain and functionality break then.

Fixes #9382
Closes #9383
