(PUP-3702) fix zone type on solaris10

Solaris10 does not inherit /sbin from the global zone by default.
This makes the zone un-bootable (ensure => running fails).
Add inherit => "/sbin" as a default to make solaris10 operate like
solaris11.
fixup the quotes on some tests to make them more consistent
on some occasions i've seen things get moved around by the shell/beaker inside double quotes in these types of commands.  most of the other tests use single quotes here.  it was more important when i had a work around in the test.  i can remove if these changes are overly superfluous .
