guix system: Properly report Shepherd errors when upgrading services.
Fixes regression introduced in 8bf92e3904cb656d4c2160fc8befebaf21a65492.
Reported by myglc2 <myglc2@gmail.com> in <http://bugs.gnu.org/24135>.
* guix/scripts/system.scm (with-shepherd-error-handling): Rename 'body'
to 'mbody'. Expand to a monadic procedure that runs MBODY.
