[OE-core] [PATCH 2/3] oeqa/utils/sshcontrol: tweak ssh options

[Mihai Lindner]

Add ssh_options to be used, the same, by ssh and scp:
Decrease LogLevel to ERROR, to suppress warnings (e.g. ssh host
verifications, two warnings in case of having openssh with hpn patches);
We no longer presume that the first line is a warning.
