SSCHECK and FIREWALL only run against a sosreport directory

[rfc1459]

Trying to run xsos -FSx on a live system fails because both modules unconditionally look for sosreport files:

# xsos -FSx
SS CHECK
  Sessions:
    Proto Local Peer sock_drop app_limited dsack_dups lost reord_seen back_log retrans_total rq tq %CPU %MEM User Command
    ----- ----- ---- --------- ----------- ---------- ---- ---------- -------- ------------- -- -- ---- ---- ---- -------

FIREWALL

/usr/local/bin/xsos: line 3760: /sos_commands/systemd/systemctl_status_--all: No such file or directory

Looking at the relevant source, the code for handling a live system is missing (using SSCHECK as an example, FIREWALL has the same issue):
