xen: Fix chardev listen sexpr formatting

'listen' isn't a valid qemu-dm option, as reported a long time ago here:

https://bugzilla.redhat.com/show_bug.cgi?id=492958

Matches the near identical logic in qemu_conf.c

v2: When parsing sexpr, only match on ",server", rather than
    full ',server,nowait'.
