[OSSTEST PATCH] ts-hosts-allocate-Executive: Do not allocate specific host with wrong blessing

[Ian Jackson <ian.jackson@eu.citrix.com>]

If the job contains a runvar specifying a specific host, still check
that host's blessing.  Otherwise bisections can run on unblessed
hosts.  They should fail instead.
