Per my own testing on dozens of SmartOS VM's and issue #473 "Problem
3", the salt-minion service manifest definition doesn't work. This
change fixes that. I think it may have broke in 2014.7 so back porting
to that ver.
Manifests in pkg/solaris are using /etc/salt which is innapropriate
for SmartOS design (/etc is removed @reboot). I suggest to add a
new directory in order to preserve existing Solaris installations
(and SmartOS one which are based on those manifests).
