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.
