[PATCH 01/20] hmp: Simplify how qmp_human_monitor_command() gets output

[Markus Armbruster <armbru@redhat.com>]

Commit 48c043d0d1 "hmp: human-monitor-command: stop using the Memory
chardev driver" left us "if string is non-empty, duplicate it, else
duplicate the empty string".  Meh.  Duplicate it unconditionally.
