    tools/xendomains: Restrict domid pattern in LIST_GREP
    
    The xendomains script uses the output of `xl list -l` to collect the
    id and name of each domain, which is used in the shutdown logic, amongst
    other purposes.
    
    The linked commit added a "domid" field to libxl_domain_create_info.
    This causes the output of `xl list -l` to contain two "domid"s per
    domain, which may not be equal. This in turn causes `xendomains stop` to
    issue two shutdown commands per domain, one of which is to a duplicate
    and/or invalid domid.
    
    To work around this, make the LIST_GREP pattern more restrictive for
    domid, so it only detects the domid at the top level and not the domid
    inside c_info.
    
    Fixes: 4a3a25678d92 ("libxl: allow creation of domains with a specified or 
random domid")
