runtests: skip starting the ssh server if user name is lacking

[bagder]

Because the ssh server startup script requires a user name there's no
point in invoking it if no name was found.

Fixes #9007

I don't understand, you're saying that this fixes #9007, but what does the ssh server has to do with the test 587 failure I've reported in #9007?

Test 587's script has code such as:

<server>
http
</server>
<name>
HTTP multi-part formpost with aborted read callback
 </name>
 <command>
http://%HOSTIP:%HTTPPORT/%TESTNUMBER
</command>

... and the protocol section also seems to be an HTTP POST request.

So it just seems to be an HTTP test, and nothing to do with SSH or SFTP?

I'm not saying it's not worthwhile to fix this SSH issue, I'm just saying that it doesn't seem like it will fix #9007?

Let's not discuss #9007 in #9013, especially not if this is not a fix for it

I believe I was discussing #9013, specifically this part of the commit message (which I quoted on the first line of my comment):

Fixes #9007

If you don't remove that line from the commit message of this PR, then when/if this PR is merged, Github will close #9007 automatically, despite this PR not being a fix for #9007.

Right, so I didn't.
