Add Solaris support

Add Solaris support
add solaris10 and solaris11 to this hash. Will also need to add keys for rsyslog_sysconfig and conditional logic so that it can check for the existence based on system type. Same thing for rsyslog_logrotate_d_config.

should also check that provider is set to 'pkgutil' if :kernel is Solaris and is `nil` for everything else.
