[OE-core] [PATCH] lib/oeqa: sshcontrol: fix false timeout failures

[Stefan Stanacar]

Ocasionally AB shows odd false fails like:
http://autobuilder.yoctoproject.org/main/builders/nightly-arm/builds/1/steps/Running%20Sanity%20Tests/logs/stdio
This should fix that by checking for eof instead of
polling the return code of the ssh process, because the process
might still be there.
