SmartOS/Solaris: fix SMF service management

fixes saltstack/salt#10702

The functions previously named get_enabled and get_disabled
actually only queried what services were running or not

This caused breakages where a state that both requested
"enabled" and "running" could cause salt to start the
service which would make it appear in the list of
enabled services, but not actually get enabled
and thus not actually come back up on reboot

Those functions have been renamed to get_running
and get_stopped

An accurate get_enabled function has been written
which queries the true property that determines
if a service will come up and boot
and get_disabled returns its negation.

New get_enabled and get_disabled functions have
also been written which accurately return the
list of enabled or disabled services
Those functions return full FMRIs (rather than the
much shorter 'SVC' column) because that's how
SMF actually works internally.
