[bug#40647] [PATCH] shepherd: remove local call/ec definition.

[guy fleury iteriteka]

Tests pass with guile 2.2 and 3.0.
I haven't test it with guile 2.0 version.

* modules/shepherd/args.scm(module): import (ice-9 control) module.
* modules/shepherd/service.scm: Likewise.
* modules/shepherd/support.scm(call/ec): remove call/ec definition and
  his exportation.
