Fix json include (#154)

* build: remove oslogin_sshca from binaries list

Remove oslogin_sshca from the list of binaries as it is not a binary
but a shared object.

* utils: don't directly include json libs header

We want to have the opaque include in the case of json lib headers,
we've seen a shift of these header over the years by hiding them
behind json.h allows us to not have to handle backward compatibility
include strategies - being able to build for older systems such as
el8.
