guestfs: increase SSH config timeout for Fedora on Debian hosts

Fedora guests running on Debian hosts timeout after 60 seconds while
waiting for network configuration during first boot. The 60-second
timeout is insufficient due to slower boot times caused by SELinux
permissive mode initialization on non-SELinux hosts.

Increase the default timeout from 60 to 180 seconds to
accommodate Fedora boot times. Make the timeout configurable via
KDEVOPS_SSH_CONFIG_TIMEOUT environment variable for flexibility in
different environments.

Improve the error message to include the configured timeout value and
suggest using 'virsh console' for boot diagnostics.
