(PUP-3057) ensure acceptance tests run on sol10

* fixup solaris10 config file
* add forge_host to options file so tests can run outside rake
* confine IPS tests to solaris11
* skip zone tests as there is not enough drive space on our solaris10
    machines (QENG-1351)
* remove grep -q option for cross-platform sanity

filed another ticket (pup-3515) to get acceptance running on a solaris10 master.  i'm not really sure i see the point?  master isn't supported on solaris, if i recall.    actually i'm sure all these 'agents.each' calls isn't helping our test cost and duplicating un-needed tests.
