(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

i think for now i'll just remove the forge_host addition and we can file some other tickets on refactoring the options/rakefile.    look for new commit this afternoon.
