guix system: Honor the build options in 'delete-generations'.

Browse source 
Until now, 'guix system delete-generations' would ignore OPTS; for
example, it would not enable #:print-extended-build-trace? & co.,
leading to suboptimal output.

* guix/scripts/system.scm (process-command)[with-store*]: New macro.
Use it for 'delete-generations', 'switch-generation', and 'roll-back'.
