WIP: add collection of OpenSSH Include config files

[jiri-belka]

Hi,
we do not collect config files defined in OpenSSH configuration via `Include'.

Should I loop multiple times for Include ???

An example:

#==[ Configuration File ]===========================#
# /usr/etc/ssh/ssh_config
Include /etc/ssh/ssh_config.d/*.conf
Include /usr/etc/ssh/ssh_config.d/*.conf
Host *
    ForwardX11Trusted yes
    SendEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES
    SendEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT
    SendEnv LC_IDENTIFICATION LC_ALL
    SendEnv LC_TERMINAL LC_TERMINAL_VERSION
    SendEnv COLORTERM TERM_PROGRAM TERM_PROGRAM_VERSION


#==[ Configuration File ]===========================#
# /etc/ssh/ssh_config - File not found

#==[ Configuration File ]===========================#
# /usr/etc/ssh/sshd_config
Include /etc/ssh/sshd_config.d/*.conf
Include /usr/etc/ssh/sshd_config.d/*.conf
AuthorizedKeysFile      .ssh/authorized_keys
UsePAM yes
X11Forwarding yes
PrintMotd no
Subsystem       sftp    /usr/libexec/ssh/sftp-server
AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES
AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT
AcceptEnv LC_IDENTIFICATION LC_ALL
AcceptEnv LC_TERMINAL LC_TERMINAL_VERSION
AcceptEnv COLORTERM TERM_PROGRAM TERM_PROGRAM_VERSION


#==[ Configuration File ]===========================#
