[PATCH OSSTEST] ts-hosts-allocate-Standalone: abort if the host to use has changed

[Ian Campbell]

When a job has been run once then the selected host is stored in a runvar and
used from then on. This means that if you try to run on a different host (by
changing the config or by changing OSSTEST_HOST_HOST) then you may be
surprised when things happen to the original host and not the new one.

Abort when this is detected.

Changing host requires you to run:
    ./cs-adjust-flight -v $flight runvar-del $job host
$flight = standalone by default
$job = test-x-y-z or build-x etc
host = the literal string host (not either of the host names)

Ping?

(TBH, I thought you had replied to this, but I can't find any mails,
sorry if I've just misplaced them)
