* guix/scripts/refresh.scm (%options)[list-dependent]: Allow an
optional argument. Set 'LIST-DEPENDENT-MACHINE-READABLE? to
#T in RESULT if the argument is "packages".
(list-dependents): Support #:MACHINE-READABLE?.
(guix-refresh): Pass #:MACHINE-READABLE? #T to LIST-DEPENDENTS if
'LIST-DEPENDENT-MACHINE-READABLE? is #T.
