connection: ignore errors when parsing ssh_config

The new ssh_Config feature doesn't work on my system because the lib
fails to parse configs using Match[1]. However Fedora and RHEL based
distros seem to ship /etc/ssh/ssh_config.d/50-redhat.conf which contains
a Match line thus it always fails to parse and never uses the proper
values from my home dir config.
