Subject: Build NIF C code also on tests

* This patch ensures building the NIF code under`c_src`
  even on running `make tests`

* When `c_src/Makefile` exists:
    * Split the Makefile invocation dependency into `app-c_src`
    * Invoke `app-c_src` also in `test-build` as well as `app`
* When `c_src/Makefile` does not exist:
    * Add `$(C_SRC_ENV) $(C_SRC_OUTPUT)` dependencies to `test-build`
