In torture_reload_sshd_server(), instead of trying to use SIGHUP to
reload the configuration file, kill the original process and create a
new one with the new configuration. With this change, both
torture_setup_sshd_server() and torture_reload_sshd_server() need to
start sshd, with the only difference in the configuration setup. The
shared code to start the sshd server was moved to a new introduced
internal function torture_start_sshd_server().
