rtpengine: work around sporadic build failures

The rtpengine build system uses the Makefiles to generate source files
on the fly. This usually works fine, but when building in parallel,
intermittently the generated files contain garbage (like, lines are
repeated, causing redefinition errors).

As a workaround this commit disables parallel builds.
