shepherd: Remove dependency on (guix utils).
Since commit 8ce6f4dc2879919c12bc76a2f4b01200af97e019, importing this module in a gexp would pull in (guix config) from the host, thereby leading to non-reproducible derivations. Users in (gnu services ...) do not expect that so simply remove the (guix utils) dependency for now. * gnu/build/shepherd.scm (fork+exec-command/container)[strip-pid]: New procedure. Use it instead of 'strip-keyword-arguments'.
