services: mcron: Validate jobs even in the presence of #:user.
Fixes a bug in 949672c923b6a3953471c446e0b19f30be335572 whereby jobs specifying a #:user not available in the build environment would fail validation. Reported by Maxim Cournoyer. * gnu/services/mcron.scm (job-files)[validated-file]: Add "prologue" file and pass it to 'mcron --schedule'.
