Add code for genkernel worker

In the future, genkernel will perform tasks such as compilation or unpack
in a separated process, primarily to allow for sandbox usage, similar how
portage executes ebuilds.

Each task will have its own "worker" script.

This commit will add the code required to run such a worker.
