(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

Maybe what we want then is to pull the default options from the Rakefile, and make an actual config/options.rb which slurps either git/options.rb or package/options.rb depending on the TYPE env variable...or does Beaker expose any of its state when it loads the options.rb (possibly allowing us to make a choice at that point about whether we are installing from git or packages?)
