guix system: Fix 'describe' when booting the latest generation.
Fixes a regression introduced in
9679123ce083c69cdfd1505d95a4066d41280394, whereby 'guix system describe'
would error out when /run/current-system points to /gnu/store/…-system,
which is the case when booting the latest generation or after
reconfigure.
* guix/scripts/system.scm (process-command): For 'describe'. Try
'generation-number' with and without the optional argument.
