services: shepherd: Spawn services with nothing but the PATH variable.
Previously, services spawned with 'make-forkexec-constructor' & co. would all inherit the environment variables of PID 1, which includes things like 'BOOT_IMAGE'. This change resets it to the bare minimum. * gnu/services/shepherd.scm (shepherd-configuration-file): Add call to 'default-environment-variables'. Remove 'setenv' call.
