this is mostly a test and example for the libexec helper infrastructure, but it also lets us simplify pager launching until we we can more easily handle executable-not-found errors the launch fallbacks would cause when using runProgram2 instead of fork. ideally we'd use `posix_spawn` later. fixes #1104 Change-Id: Ia33cc12e8a9d60ffad6f5c055bb1b8b596810e64
